Installing the Control Components
Throttle Control
☐
Using cable ties, secure the throttle control under the dashboard, away from
moving parts and positioned so that the buttons and LED lights are accessible.
☐
Unplug the OEM cable from the accelerator pedal and plug it into the matching
connector from the throttle control. Plug the cable from the throttle control into
the matching connector on the accelerator pedal.
☐
Connect the green wire with ring terminal (running from the throttle control) to
a good ground.
☐
Locate the OBD II port (generally located under the dashboard, beneath the
steering wheel column).
☐
Remove the fasteners securing the OBD II port to the dashboard; this provides
easier access to the wires at the back.
☐
Peel back the tape on the harness a few inches.
The wires populating pins 6 and 14 are a twisted pair (violet with
white stripe and violet wires).
☐
Locate the violet wire with white stripe connected to pin 6 of the OBD II port
Figure 54 — OBD II connector
☐
Cut the violet wire with white stripe approximately 2 in from the back of the
OBD II connector.
☐
Strip approximately 3/8 in from the end of both wires.
☐
Twist the light blue wire from the throttle control together with the violet wire
with white stripe; using the supplied butt connector, splice these paired wires to
the violet wire with white stripe wire at pin 6.
☐
Locate the violet wire connected to pin 14 of the OBD II port (Figure 54).
☐
Cut the violet wire approximately 2 in from the back of the OBD II connector.
☐
Strip approximately 3/8 in from the end of both wires.
☐
Twist the grey wire from the throttle control together with the violet wire; using
the supplied butt connector, splice these paired wires to the violet wire at
pin 14.
☐
Lightly tug the wires to ensure they are properly crimped.
☐
Using a heat gun, carefully apply heat to the butt connectors to seal the
connection.
