Routing the Wires of a Tail Light Isolating Diode System # 38995 From Front to Rear of Vehicle


2010 HHR LT Harness Code: 38955 I watched the video for hooking up the wiring harness. Do you have any advice how to get the wire from the front to the rear. The video left the impression that the wire ran under and came into the passenger compartment near the tail lights.

I attached an FAQ article to the right that details how a similar wiring install is run from the back of a vehicle to the front for you to check out. But basically you will want to route the wire through frame rails is present or along existing harnesses using zip ties to attach the wire avoiding any pinch points like suspension components or hot areas like exhaust pipes.

To get the wire into the interior of the rear of your vehicle you will want to find a grommet in the trunk area, cut a slit in it and then slide the end of the wiring harness through it. I attached an install video for more information for you to check out.
