My next project is to repalce the old rear body wiring harness with a new one and I'm hoping someone will tell me this is an easy project. I see that the existing harness disappears into the car just under my convertible top heding to the front of the car.

Will I have to remove the drivers seat and back seat to gain access to the harness? Also...does this harness plug into the fuse panel or is there an existing connector the harness plugs into. I looked at the fues panel and only noticed two harnesses pluged into it. One for the front lights and the other for the wiper/blower motor.

I did order a wiring diagram from Rick's hoping it would show me where this thing goes to but it has not arrived yet. By the way...I'm not sure if I can do this but I feel the need to "Pimp" Ricks a little bit. I've ordered several things from them in the past and they do a FANTASTIC job!

Thanks in advacne for any direction.

I think you will find it easier to remove the drivers and rear seats, the sill plate on the drivers side, then roll back the carpet and remove the metal covers that are over the harness. If my memory is correct, the rear harness plugs into a connector behind the drivers door hinge post (behind the kick panel). Hope this helps.

Thanks for the reply Ragtop. Ive been researching this all day and I'm amazed at how little info is out there.

Is there a specific reason you want to replace the whole harness? The wiring diagrams you are waiting to receive are exactly what is in the 67 AIM which I think you have downloaded already. If not, search "digital assembly" here and download from one of the current links toward the end of the multi-page thread.

There are at least three or four separate harnesses, depending if your car is a power top and/or has the optional trunk light.

The "intermediate" or "front to back" harness is the one that connects to the main underdash harness behind the top of the kick panel or under the dash as described above (67 AIM electrical UPC section will show exact location for 67 model).

If you have a power top, there is a separate harness for that. Should be covered in the 67 AIM under the power top RPO number.

If you have a trunk light, there is a separate harness for that too. Covered in the 67 AIM for auxiliary lighting RPO U- something.

The front to back harness runs into the trunk, and has a plug on the driver side where the rear lighting and fuel gauge harness connects. Again, shown in 67 AIM in electrical UPC section.

If you are having some specific electrical problem and need to inspect/troubleshoot, if you tell us what is happening we might help you focus.

If you do end up needing to uncover the whole front to back harness, you should not need to pull the driver seat. You will have to take off the sill plate on the driver side, remove the driver side kick panel (which will also involve removing the parking brake assembly, and a whole lot of pulling and cursing and probably bleeding), plus the back seat bottom and top, plus the upper cover and armrest on the driver side. You will probably have to pull the rear door opening windlace loose at the bottom if the carpet is tucked under, but once all that stuff is removed, you can roll the carpet up along the driver seat side and then remove the screws that hold the galvanized wire gutter covers in place over the channel the front to back harness is secured in.

Hi Eric,
The rear wiring harness is very old and I would not be surprised if it's the original. The reason I'm replacing the harness is the backup lights do not work ( I did replace the neutral safety switch which did not solve my problem). Now..I have tail lights that only work part of the time so I'm guessing a new harness would be a good idea.

I do not have a power top or rear deck light.

I do have the AIM and did read the section concerning this particular item but was unable to tell if the rear harness plugged into a connector somewhere or directly into the fuse box. I'll also take a look at the threads you suggessted.

Thanks for your reply.

Dean do you have the Fisher Body Manual?
Anything installed by them which is with a few exceptions everything from the cowl back excluding the dash, and carpet, but including that harness is covered in their manual. It has tons of photos too unlike the AIM.
