Installation
Note: Our installation detail is less
complete than the directions that come with
the unit. This article is meant to
outline and give a better idea of the
installation. Follow the Unichip
directions and this guide together.
Disconnect the battery. Messing with
the computer systems on newer vehicles can
be risky without some precautions. Not
remembering to disconnect the power can
cause damage to the computer system.
Locate the Jeep's computer on the drivers
side behind the windshield washer bottle.
Pop the two retaining clips that hold the
computer plugs in place on the outer most
two plugs. Some model Jeeps use four
of the plugs others use three.
When the plug clips are released squeeze the
black tab to the rear of the red retainer
and gently rock the plug to release it.
Repeat for the second plug. You will
notice the outer connector is black and the
second is orange.
Next, install the Unichip wiring harness
into the original plugs. Plug the
orange connector into the orange plug and
the black into the black. Then plug
both connectors back into the computer.

Install the
module - a modification
The directions call to attach a Velcro patch
to the back of the module and attach it to
the plastic area on the front of the brake
control. We didn't like the way the
module was crammed into the area and made it
almost impossible to remove the wiring
harness. We fabricated a piece of flat
aluminum and created a bracket to mount the
chip above the brake control.
A piece of rubber was attached to the bottom
of the plate to prevent it from rubbing the
brake lines. Two screws into the
plastic inner fender and a wire tie keep the
module securely in place.
Reconnect the battery - the Jeeps horn will
beep and the wipers may move - don't let it
startle you. Start the Jeep and see
that it idles and sound correct. If it
doesn't start disconnect the battery and
verify connections. Follow the
troubleshooting procedure outlined in the
Unichip directions.
