I replaced the “main” wiring harness today. The wiring harness that was in the car got some over-paint on it while I was doing the undercoating of the car last summer. I should have removed the wiring harness before doing that, but I didn’t. Live and learn I guess. No one would really see the paint on most of the wiring harness, since most of it is hidden anyway. I would have known though, and it was bugging me. I ordered a new “main” wiring harness from Wiring Works and it arrived today. It was pretty easy to replace and only took me about an hour to do. The main thing I did was make note of where all the connections went. I did this by taking pictures. I then unhooked the wiring harness from the fuse panel and tied a rope to it using electrical tape. I pulled the wiring harness out through the back of the car, along with the rope. Once the old wiring harness was out, I taped the new wiring harness to the rope and pulled it back through. I probably went a little overkill on the electrical tape to hold the rope to the wiring harness, but better to be safe than sorry. I really didn’t have to pull too hard on the rope to get the new wiring harness through. The main part where I needed the rope was in the rear quarter panel and not a lot of pressure was needed to pull it through. I don’t have pictures of the new wiring harness installed, but here are a few of the rope in the car, along with a shot of the new wiring harness being pulled through the rear quarter panel near the back seat. I also included a few pictures of the old wiring harness and the paint that was on it (Am I too anal?).
Tracer rope taped to old wiring harness in front luggage compartment…
Old wiring harness pulled through hole in front luggage compartment to inside of car. Rope following along behind (man, I need to dust!)…
Picture from inside of car. Same hole as in last picture. You can see the rope has been pulled through along with the old wiring harness. You’ll need to pull the carpet back a bit to get in there…
The wiring harness runs under the driver side door sill carpet. You’ll need to pull that back a little bit…
The old wiring harness has been pulled through the rear quarter panel into the engine compartment. Here’s the rope…
The old wiring harness is out, and the rope runs all the way from the front luggage compartment back to the engine compartment. You can see a little bit of the foam insulation from the rear quarter panel has fallen into the engine compartment. No biggie, just wipe it away. Time to tape up the rope to the new wiring harness…
Pulling the new wiring harness through the rear quarter panel. I used a lot of tape to hold that rope to the wiring harness…
Here are some pictures of the *OLD* wiring harness out of the car. Probably didn’t need to replace it, but I’m pretty picky I guess… 😉
You can see where I taped the tracer rope to the old harness. I just cut the rope once it was pulled through, instead of trying to untape it from the old harness. No point in wasting time on the old harness by carefully removing the tape. 😉
