Accessory Line Connection
Most vehicles have a separate accessory line to power the radio, electric windows, etc.
1.Turn on the vehicle’s radio and rotate the ignition key to ACC. The radio should turn on.
2.Locate the one wire that carries +12V only when the ignition key is in the ACC and ON
positions, but 0V while the key is in the START position.
3.Cut this wire, then start the engine. The radio should not operate.
4.Connect the 12-pin connector’s ORANGE wire to the accessory wire as shown on page 4.
Secondary Ignition or Heater/AC Wire
Many vehicles have two ignition or two heater/AC wires in order to split up the power
requirements of the temperature control system, onboard computers, fuel delivery system,
electronic transmission control, etc. If you are working on such a vehicle, you will find two
wires that both test as ignition lines or two wires that supply the heater/AC:
1. Connect the BLUE/BLACK wire to the coil of a relay for the second heater/AC line.
2.Connect the BLUE/ORANGE wire to the coil of a relay for the 2nd ignition line.
LED Status Indicator
Select a prominent location on the dash or console. Discuss placement with the owner.
1.Verify there is adequate space to accommodate the LED, then drill a 5/16” (8mm) hole
and route the wires through it.
2.Mate the LED connectors to the VIOLET and BLACK wire connectors as shown in the
diagram on page 5.
3. Press the LED into place.
PlainView 2 Coded Valet/Programming Switch
1.Discuss placement of the switch with the vehicle owner and avoid placing the switch
where it can be pressed accidentally.
2.Verify there is adequate space behind the selected location to accommodate the switch.
3.Drill a 5/16” (8mm) mounting hole, then insert the wires through the hole.
4.Mate the switch’s locking connectors to the WHITE and BLACK locking connector.
5.Remove the adhesive backing and press the switch into place.
Door Trigger/Interior Light Supply
The ACE 7500 has self-programming door trigger polarity. Door triggers on most autos are
negative (except most Rolls-Royce and Ford autos). To determine door trigger polarity, use
the following procedure:
1.Find the wire coming off the rear of the vehicle door switch.
2. Connect the negative voltmeter lead to ground.
3.Find the one wire that shows +12 volts when the switch is pressed in and 0 volts when
released. This is a negative trigger door wire.
4.If you don’t get the indications noted in step 3, find the one wire that shows 0 volts when
the switch is pressed in and +12 volts when released. This is a positive trigger door wire.
5.Connect the system’s thin GRAY wire to the door wire.
6.If the trigger wire is negative, connect the system’s BROWN/RED interior light supply
wire to ground. If the trigger wire is positive, connect the system’s BROWN/RED interior
light supply wire to the RED/WHITE wire.
