I got an 84 last week with wiring issues. Many of the wires under the hood have the insulation missing or falling off. I've looked at the wiring on the steering column and it all looks good so I believe the wiring issues are due to the underhood heat. So I need to do something with it before I'm going to risk hooking the battery up. With the way the insulation is falling off I have to believe that depinning the connectors 1 wire at a time and applying heat shrink probably won't work because the insulation will also be falling off internal to the harness. Also with the insulation having been gone for an extended period the bare wire is corroded.
So my next idea was to use parts of a TC harness. I have scrapped a pair of 87/8 TC that I pulled the harnesses from. While I can see many of the connectors are different and in different places I'm hoping I can make something work. While I'm at it I'm probably going to upgrade the injectors and go to an L series ECU.
Anybody done something similar to repair an 84 harness?
