Rewiring a 72 Z??

[ErikLS2]

First thing is to try not to be intimidated, although I know wiring a whole car can be. If you can wire up one circuit, you can wire up all of them. Just do one circuit at a time and start with the easier ones first and try not to look at all those wires at the same time if you can.

Install the fuse block and then pick a circuit and work your way out from there. I would initially just get the wires laid out in their basic location before you connect anything. Inevitably you'll discover you wanted a harness routed slightly differently than you initially lay it out.

Make sure the harness is protected with that plastic conduit around any sharp edges or where it could wear through. Make sure there is no tension on the harness near connectors and that the harness is secured enough to not move around. It wouldn't hurt to add a few restraints in areas where the harness hangs loose or flops around some. A little dielectric grease on connectors that could get wet will help prevent corrosion too.

Once everything is connected, test every circuit and gently wiggle and tug on the harness and connectors to make sure you don't have any poor connections. Also make sure all your ground connections are to bare metal. The ground side is as important as the rest of it.

Good luck and let us know how it goes!
