WARNINGWARNING
ASTROSTART™ RS-504 system is designed for use in all manual shift transmission, gasoline or diesel
powered, fuel injected vehicles.
Carbureted or throttle-assisted vehicles need an optional solenoid kit.(part #310-050-501)
Diesel vehicles need a Diesel Tach Sensor DTS-1 (part #310-066-500).
Do not install in vehicles equipped with a automatic transmission.
VEHICLEPRE-CHECKVEHICLEPRE-CHECK
Prior to installing the unit, go through this checklist carefully:
• Is the starter in good working condition?
• Is the battery fully charged?
• Does the climate control system work properly?
• Are the parking lights and horn functional?
• Are the hand brake, and the “BRAKE” indicator functional?
• Has the ASTROSTART™ switch been set to the OFF position prior to installation?
• Is the power door lock system (if used) working properly (some vehicles do not have a drivers door motor)?
BEFOREYOUBEGINBEFOREYOUBEGIN
Installing the ASTROSTART™ system is a simple step by step process. Take the time to review each step.
For a trouble free installation follow these guidelines:
• Carefully review the installation instructions and wiring diagrams.
• Solder all electrical connections.
• Probe and confirm every connection before soldering.
• Do not try to use the ASTROSTART™ before programming the unit properly.
• Do not cut or splice any of the ground wires. Use ring terminals to ground each wire to the chassis of the
vehicle.
• Probing unknown wires with a test light could damage the vehicles electrical system. To probe safely, use a
voltmeter or the ASTROSTART™ Multitest tool.
• Never disconnect any Air Bag circuits when probing wires at the steering column, serious damage can occur.
VEHICLEPREPARATIONVEHICLEPREPARATION
• You must first prepare the vehicle as follows:
• Leave the drivers door window open and remove the dome light fuse.
• Expose the under dash wiring on the drivers side by removing any panels blocking access.
• Find a suitable location under the dash for the ASTROSTART™ module. Do not locate close to any moving
parts (brake pedal, steering column, gas pedal, etc...).
• Make sure that the transmission shifter is in the “NEUTRAL” position.

PINSWITCHINSTALLATIONANDWIRINGPINSWITCHINSTALLATIONANDWIRING
HARNESS#253HARNESS#253
The Pin Switch is installed to prevent the vehicle from starting with the hood open. This important SAFETY
precaution prevents the possibility of the engine starting by mistake when the vehicle is being serviced. This
feature will also shut the engine off immediately if someone attempts to open the hood after the vehicle has
been started by remote.
PINSWITCHMOUNTINGPINSWITCHMOUNTING
• The switch must be mounted in contact with the chassis (ground) of the vehicle
• The switch must line up with the hood so that the hood pushes down on the switch (disconnects contact to
chassis of vehicle) when it closes.
• Connect the BLK/RED wire on harness #253 to the pin switch.

193-504-121-00 4L25 PAGE 5
PINSWITCHTESTINGPINSWITCHTESTING
• Close the hood.
• Set your voltage meter to the "Continuity" mode
• Attach one meter probe to the BLK/RED wire, attach the other meter probe to the chassis of the vehicle.
• With the hood closed there should be no indication of continuity to the chassis of the vehicle.
• Open the hood
• With the hood open the meter should indicate continuity to chassis ground.
• If the pin switch does not work exactly as outlined above you will have to readjust.
Caution: Advise your customer of the importance of maintaining this switch in good working
condition. Ask the customer to check switch operation at least once every month. by performing the
following tests;
Ø Start the vehicle by remote control,
Ø Than releasing the hood. The engine should shut off immediately,
Ø If this does not occur the customer should return to your installation facility immediately.

HARNESS#252HARNESS#252
This connection enables the ASTROSTART™ system to monitor engine R.P.M (Revolutions Per Minute). This
information is used to determine when to disengage the vehicles starter motor, and to shut the engine off when
the engine R.P.M becomes too high.
The RS-504 will display the tach pulses after enabling the function via the programming mode.

B) THEMULTICOILDISTRIBUTORLESSSYSTEM
The multicoil distributorless system is similar to the one on the diagram below. Two, three or four coils are
located in the same control module with four, six, or eight spark plug wires exiting the module. Connect the
BLK/GRN wire to the PULSE INPUT wire at the module. (Wire that gives a tach signal)
In certain cases, there will be two white wires coming from the module. When tested using the MultiTest, both
wires will have a tach signal. Use the wire where the tach signal appears sooner while cranking the engine.
C)OTHERMULTICOILSYSTEMS
All other multicoil ignition systems have one, two, four or six cylinders per coil and each coil's negative terminal
is available for tach signal. This means that a three coil, six cylinder vehicle has three tach wires each
providing a tach signal for two cylinders. Connect the BLK/GRN wire to one (1) of the ignition coils.
• Program your ASTROSTART™ system to the setting corresponding with the number of cylinders that each
ignition coil services. eg. A three coil, six cylinder vehicle would be set for two (2) cylinders.

• Locate the brake switch.
• Find the N.O. (Normally Open) brake switch wire (the wire that indicates +12V only when the pedal is
depressed.
• Connect the WHT/GRN wire on harness #253 to this wire.
Note: Some vehicles require the ignition to be ON in order for the brake lights to work. Keep this in
mind when locating the N.O. brake switch wire.

CLUTCHSWITCHOVERRIDINGCLUTCHSWITCHOVERRIDING
In most manual shift transmission vehicle’s, the clutch must be held down to start the vehicle. Your remote
starter must simulate this operation. It is necessary to add a relay that shorts the clutch contacts only when
starting by remote.
WIRINGWIRING
• First, find the clutch switch located on top of the clutch pedal.
• Determine witch type of switching is used.
• Make connections according to the corresponding diagram below.
Following are the two types of switching most frequently used by vehicle manufacturers.
The clutch switch is used as a normally open contact to disable the starter by :
• Type # 1: cutting the starter circuit from ignition (see diagram # 1).
• Type # 2: cutting the wire that controls the starter relay from ground (see diagram # 2).
Never use a jumper to by-pass the clutch switch.
The clutch switch is the main security device featured by the manufacturer.
By-passing this switch could result in injuries to the user or its environment.

HARNESS#251HARNESS#251
Begin by locating the main IGNITION circuit of the vehicle. This factory harness is located behind the
IGNITION key of the vehicle. These wires are usually the largest gauge wires under the dash and are
easy to find. SOLDER ALL CONNECTIONS.
RED - Main Battery Power (+12V Input)
Locate the largest gauge +12V power source at the IGNITION key harness. Solder the RED wire to
this circuit. This is the main power supply to the ASTROSTART™.
ORG - Ignition Output (+12V Output before, during, and after cranking)
Locate the largest gauge wire that shows +12V when the key is in both the RUN and START
positions.♣Solder the ORG wire to this circuit. The ORG wire supplies +12V to the ignition circuit
four (4) seconds before cranking and while the engine runs by remote.
DK/BLU - Start Wire (+12V Output while engine is cranking only)
Locate the largest gauge wire that shows +12V ONLY when the engine is cranking. ♣Solder the
DK/BLUE wire directly to this circuit. The DK/BLU wire provides +12V to the starter solenoid, this
activates the starter motor.
If the starter wire passes through the clutch switch contacts, connect this wire to the contact that goes directly to the
starter. See step 5, diagram # 1.
YEL - Heater/AC Control (+12V Output before & after starting)
Locate the largest gauge wire that shows +12V when the key is in the RUN or ACC position ONLY. ♣
Solder the YEL wire to this circuit. The YEL wire provides power to the Heater and Air Conditioning
systems.
BLK - System Ground Input.
This is the main ground connection and of the upmost importance to ensure reliable system operation.
Always attach the ring terminal to the vehicle's chassis behind the driver's side kick panel.
NEVER CONNECT THIS GROUND WIRE TO THE DASHBOARD.
♣Note: If you find more than one of these wires in the IGNITION key harness you may have to
interface a second circuit. See the “Special Applications”section on page 31.
GRN - Parking Light Interface (+12V Output)
This interface enables parking light acknowledgement of system operation. Locate the wire at the back
of the vehicle light switch that is live when the parking lights are operational. Connect the GRN wire to
this circuit.
Note: If the vehicle uses a negative switched signal at the master light switch it may be necessary to
connect directly at one of the parking light bulbs either at the front or rear of the vehicle.

MAINHARNESSTESTMAINHARNESSTEST
Once you have made all the necessary connections to harness #251, you are ready to proceed with a quick test
of these circuits. Using a split jumper make the following connections as illustrated in the diagram.
1) Ignition Test - Connect the RED and ORG wires using the jumper. Leave the jumper in this position until all
the tests are completed.The dash board should light up.
2) Start Test - MOMENTARILY connect the jumper to the DK/BLU wire. This connection will engage the starter
motor. When performing this test, make sure that you remove the jumper from the DK/BLU wire the instant
that the engine starts up. Leaving this wire connected will damage the starter motor.
3) Heating/AC Test - Connect the RED and YEL wires using the jumper. This connection will engage the
climate controls of the vehicle. Test all climate control functions for proper use.
4) Parking Lights Test - Connect the RED and GRN wires using the jumper. This connection will engage the
parking lights.
5 ) Totally Disconnect The Jumper - All functions should stop operating.

HANDBRAKEHANDBRAKE
This connection monitors the hand brake status. It disables the system when the hand brake is not applied or
released.
Most vehicle’s hand brake monitoring circuits use negative switching. (ground when hand brake is applied).
To avoid any ground feed-back from the vehicle’s circuitry, you must add a diode in the circuit following the
diagram below.
Ø Cut the hand brake wire.
Ø Solder the negative side ( side marked with a white trace) of the diode (1N4004) to this wire toward the hand
brake switch.
Ø Solder the positive side of the diode to this wire toward the “BRAKE” indicator.
Ø Solder the GREEN wire of harness “R” at the hand brake switch.
For positive switching circuits, solder the diode in the opposite way (negative terminal toward the
“BRAKE” indicator). For programming positive switching detection refer to “SND-1 MODULE” in
the “PROGRAMMING” section on page 43.

Ø Then locate on the transmission shifter, in the “NEUTRAL” position, the lowest location where the
transmitters will be installed. (Visual contact must be possible with the receivers installed on the floor.)
Ø Make sure that the chosen location will not disturb the shifter dust boot. A constant friction on the boot will
cause damage to it, or alter the adjustment of the sensors.

Ø Once you have determined the location where all the components will be installed, you may continue with
assembling the fixture.
Ø Refer to the following diagram to assemble the two receivers on their fixture.
Ø Then fasten both receivers at the base of the transmission shifter on the pre-selected location, making sure
that visual contact with the transmitters will be possible once installed.
Note: Use only one screw on the fixtures, this gives you the possibility to rotate the fixtures during final
adjustments .

Refer to the following diagram to assemble the two transmitters on their fixture.
When both transmitters are mounted, you may fix it temporarily using the two sided tape (included in the kit)
then continue with the alignments. The sensors are matched in pairs, these pairs are identified by their wire
colors. E.g.: The transmitter with the BLACK/WHITE wires matches with the receiver with the BLACK/WHITE
wires. When installing the sensors make sure that the pairs are matched.
Note: The two sided tape supplied takes approximately 48 hours to get its full strength. You have plenty
of time to complete the alignments.

193-504-121-00 4L25 PAGE 17
SENSORALIGNMENTSENSORALIGNMENT
A perfect alignment of the sensors is extremely important. There are different ways to do so at your disposal:
ALIGNMENT USING THE L.E.D.
Ø The SND-1 module has two LEDs to adjust the sensor’s position. One per sensor pair.
Ø When DIP # 1 on the SND-1 module is in the “ON” position and the brake pedal is depressed, the module
goes into the adjustment mode.
Ø The module generates two beeps each time the brake pedal is released to indicate that the module is in the
adjustment mode.
Ø When in this mode, a LED will light up when the corresponding sensor pair is aligned.
Ø When the shifter is in the “NEUTRAL” position, put DIP # 1 in the “ON” position, depress the brake pedal,
then align the receivers and transmitters in order to light up both LEDs.
Ø Remember that it is impossible to remote start the engine when the SND-1 module’s DIP # 1 is in the “ON”
position.
FIGURE A FIGURE B
ALIGNMENT USING THE SPECIAL TOOL
Ø A tool has been especially designed to help the installers in aligning the sensors.(fig b.)
Ø This tool holds the sensors in place while fastening them.

PAGE 18 193-504-121-00 4L25
ALIGNMENT VERIFICATION
Ø When every adjustment is made, put the tie wraps in place around the transmitter fixtures, and thigh lightly.
Ø Check when slightly moving the shifter in every direction that at least one LED shuts off.
Ø Check that both LED’s shuts off when the transmission shifter is in gear. See diagram below.
Ø Also make sure that the sensors cannot affect the shifter movement when this one is moved in all directions.
If so, relocate the sensors.
Ø TPut DIP # 2 in the “ON” position and check if both LEDs still light up when the shifter is in the “NEUTRAL”
position. Realign the sensors if necessary.
Ø START the engine with the key , and check if both LEDs remain lit while the engine is cranking. This
procedure is to ensure that when starting the engine, the shifter lever will not move significantly enough to
produce a START fail condition to the remote starter. If any LEDs go out during this test, relocate the
sensors to correct this situation.
Ø When all the sensors are aligned properly, you can tighten up the tie wraps around the transmitter fixtures.
Ø We recommend to apply glue (Lock-Tite or Crazy-glue) on every screw surface, then tighten mildly.
Ø Fasten the harness’ to the shifter by putting the tie wraps on the gray sleeve, not on the sensor wires. Leave
some leeway on the harness at the base of the shifter to avoid pulling on it when the shifter is moved.
Ø Fasten the harness’ to the floor, away from any mobile parts.
Put DIP # 1 and # 2 of the SND-1 module to the “OFF” position.
TIt is of the most importance that this test be done. When DIP # 2 is “ON”, it simulates a temperature of -30º C
that reduces the sensor's sensitivity. If this test is omitted, the remote starter might not work on very cold
weather.

The following section outlines "Basic Starter Installation Programming". All ASTROSTART™ models require
certain vehicle, and system configuration parameters to be entered prior to testing the system.
PROGRAMMINGPROCEDURES:
• Turn to the " Installer Programming" section on page 42.
• After the programming is done continue on next page.
PREPARINGPRIORSTARTINGPREPARINGPRIORSTARTING
The remote starter must have received a confirmation from the SND-1 module to be ready for starting.
The SND-1 module sends this confirmation by way of an audio signal (beep) each time the BRAKE pedal is
depressed without the key in the ignition switch, or each time the ignition key is turned from the “RUN” to the
“OFF” position.
Press the BRAKE pedal to generate a confirmation code from the module.
CONFIRMATION
1 beep The system is ready to receive a START command.
2 beeps System not ready. The shifter is out of the “NEUTRAL” position.
3 beeps System not ready. The hand BRAKE is not applied properly.
4 beeps System not ready. The security sequence was not recognized. T
5 beeps Harness “A” is not connected to the SND-1 module, or harness “401-A” is not
connected to the RS-504 module.
TThis sequence is part of the security features of the SND-1 module, it monitors the position of the
transmission shifter at all times.
This sequence is validated each time the transmission shifter is moved from the “IN GEAR “position to the
“NEUTRAL” position when the hand BRAKE is not applied.
If the system sends a code 4 (4 BEEPS) you must:
• release the hand brake;
• put the shifter in gear (any position);
• bring the shifter back to the “NEUTRAL” position;
• apply the hand brake;
• press the brake pedal to generate a confirmation code.
