3.1 Installing the Components
□
Install the control box where it will be accessible but will not be
subject to damage, such as under the center of the dash above
the transmission hump. Mark the position of the mounting holes,
drill two holes and mount the control box with the wire harness
coming out the bottom of the unit.
□
Mount the throttle control under the dash near the steering
column using plastic ties in a position where the harness
connectors on the throttle control will reach the OEM accelerator
connectors.
□
Route the following wires into the engine compartment through a
suitable OEM plug in the firewall. One location is the large wire
harness plug behind the park brake:
grey wire with a 3 pin black connector
grey wire with a 4 pin green connector
white wire with a plug connector
white wire with no connector
automatic transmission vehicles
– blue wire with no connector
3.2 Connecting the In-cab Wiring
□
Unplug the OEM cable from the accelerator pedal and plug it into
the matching connector from the throttle control box. Plug the
cable from the throttle control into the matching connector on the
accelerator pedal.
□
Connect the two white interface connectors together.
□
Connect the red wire from the throttle controller to the red wire
from the interface cable.
□
Connect the ground wire from the throttle control to a good
ground under the dash.
□
Remove the connector from the park brake switch, connect it to
the piggyback connector on the black wire from the interface
connector and plug it back onto the park brake switch.
