Negative switching of “Increase Revs” input:
Positive switching of “Increase Revs” input:
All inputs are monitored by on-board LEDs. The LED is lit when the input is active. Each input
contains a pair of wires – a positive and a negative. Both wires must be connected for the
input to function. By using this method, it does not matter whether your inputs are switching
positive or negative signals – the universal inputs will accept it.
The following diagrams demonstrate positive and negative switching examples using the
“Increase Revs” input.

Overview
The V5 Universal Throttle Module is designed and manufactured in Australia by WoodTech
Electronics. It is easy to install into both 12 and 24 Volt vehicles. Utilising both positive and
negative input switching, the module can be configured by the end user to suit almost any
application.
The software within the V5 Universal Throttle Module contains multiple programs and
parameters to suit various applications. The on board dipswitches allow the correct program
and/or features be selected. It is important that the correct dipswitch settings are used for your
application.
The number of dipswitches has increased from 4 to 8 in the V5 model to allow for added
features in the future. Dipswitches 1 thru 4 work exactly the same way as they did with V4 and
have the same functions. If you are replacing a V4 version with a V5 dipswitch 8 must also be
on.
Features
-Designed and manufactured in Australia by WoodTech Electronics – Over 20 Years
experience in Automotive Control Systems and Electronics.
-Wide supply voltage range: 10 – 30 Volts DC.
-Universal inputs can switch both positive or negative
-Multiple lockouts for Park Brake, Transmission in Neutral etc.
-Easily incorporated into existing E-stop (Emergency Stop) systems.
-Failsafe operation – Loss of supply or lockout activation results in immediate RTZ
(Return-To-Zero) output status.
-Engine Speed adjustment potentiometer allows the installer to easily “fine tune” the
operation. Output voltage can be adjusted from approx. 1.5 – 5.0 Volts to set maximum
engine RPM.
Installation
Select a suitable location inside the cabin to mount the enclosure. Keep away from hot areas
such as heaters and ensure there will be no fouling with moving parts (eg. wipers, control
levers etc.)
Using the supplied wiring diagrams as a guide, make secure electrical connections and
provide a good, clean earth. Always use a 5 Amp fuse in the positive supply. Use caution
when making the connections going to the vehicles’ remote accelerator connector. Double
check the wiring at this point as you do not want to damage the expensive vehicle ECU.
For manual transmission vehicles, we strongly recommend at least one of the lockouts be
connected to the Park Brake. If the selected lockouts are not active, the module will not work.
For automatic transmissions, we recommend the second lockout be connected to the Neutral
switch.

Note: The supplied wiring diagrams are correct at the time this document was written. The
factory wiring colours do not match up between the remote throttle connector and the
extension wiring harness. If in doubt, ask!
You will also need to install the parts in the Isuzu Remote Accelerator Kit. Please follow the
instructions supplied with the kit.
Recommended Settings – Manual Transmission vehicles:
Lockout 1- connected to Park Brake
Lockout 2 – not connected
Dipswitch1 – ON, All others OFF
This setting selects only Lockout 1 to be active. Lockout 2 and Lockout 3 are not used in this
configuration and therefore no connections need to be made to these inputs.
Recommended Settings – Automatic Transmission vehicles:
Lockout 1 – connected to Park Brake
Lockout 2 – connected to transmission neutral switch
Dipswitch1 and Dipswitch2 ON
This setting selects Lockout 1 and Lockout 2 to be active. Lockout 3 is not used in this
configuration and therefore no connections need to be made to this input.
Connection to Stop Light circuit:
Lockout 3 may be connected to the vehicle stop light circuit. Upon activation of the vehicle
foot brake, the module will immediately return the output voltage to the idle value.
WARNING:
Although it is possible to bypass the lockouts by leaving Dipswitch1 and Dipswitch2 switched
off, THIS MAY COMPRIMISE THE SAFETY OF THE SYSTEM. WE STRONGLY ADVISE
INSTALLATION AS PER THE ABOVE RECOMMENDATIONS.
Testing and Adjustment
Switch on ignition and ensure Park Brake is on (and transmission in neutral, if applicable). If
vehicle is a manual transmission, the Power and Lockout 1 LEDs should be illuminated. If
vehicle is an automatic transmission, the Power, Lockout 1 and Lockout2 LEDs should be
illuminated.
Operating the “Revs Increase” or “Revs Decrease” switch should illuminate the corresponding
LEDs. Also check the operation of the Park Brake lockout (and Neutral lockout, if applicable).
Remember, if the lockouts are not activated (LEDs illuminated), the module will not work.

Start the engine and engage the PTO. Activate the Increase Revs switch and the engine revs
should slowly increase. The maximum required engine RPM can be adjusted with the “HI”
adjustment. Turning clockwise will increase the RPM. Activate the Decrease Revs switch and
the engine rpm should return to idle.
The rate at which the engine revs ramp up and ramp down can be adjusted with the “RAMP”
adjustment pot. Turning this pot clockwise makes the ramp time slower. Even when set to the
fastest setting (fully anti clockwise), the vehicle ECU ultimately determines how quickly it will
allow the engine to change rpm.
Most remote accelerator applications require a voltage of approx. between 0.4 – 1.0v before
the engine will increase above idle. Because of this, there can appear to be some “dead time”
from idle as you hold the Increase Revs button. The “LO” adjustment pot “tunes out” this dead
time by setting a minimum voltage somewhere between 0 – 1.0 volts. Turning the “LO” pot
clockwise increases this initial voltage.
If the setting of the “LO” pot is too low, there will be noticeable “dead time” when initially
increasing the rpm above idle. If the setting of the “LO” pot is too high, the engine will not
return fully to idle RPM. A little time spent getting this adjustment “just right” will improve the
overall smoothness and operation of the system.
