I have my brothers main wire harness laid out here on a table. The rear light portion needs some TLC. While I'm at it wanted to delete the under the seat relay. I know just jump the yellow wire and go. I want to clean up that whole mess of wires if possible. My question is what can be deleted and what can't? I plan on adding a few wires for the 3.0 press/temp gauge and maybe a few other spares from the engine up to the gauge cluster.
Maybe Jeff B will chime in here.... @JeffBowlsby Attached image(s) |

Still messing around with the wire harness here. Got most of it figured out. It needs some tlc for sure. The ground wires by the engine relay board are toast. It looks like a few wires got hot and melted together. Still trying to figure out the cut red wire at the fuse board. I did locate a good color schematic online so I need to give it a good look over. The headlight, turn signal, fog lights, and horn wires look a little rough up front too.
Guess I could always run new wires up there. Hopefully I ordered enough wire to get the job done. All wires will be color coded like the org wires. No need to panic.. (IMG:style_emoticons/default/laugh.gif) I added a fog light switch to the dash but want it to work independently from the headlight switch. Anyone know if this rewire job will work for sure? I just want to confirm before I start cutting and adding wires for this. Also adding a hot start relay in the engine bay someplace. I'll take a look and see where I could mount it.

Hey Luke, If you are using a '74 wiring harness, the only wires shown on the schematic from fuse 8 are all Red/Blk. 1 goes to the fresh air blower indicator light, one to the fresh air blower and the 3rd to the windshield wiper switch. Is it a plain red wire? could it be something the DAPO added in? |
