im doing a frame off restoration of a 92 rs and i have all of the wires off and i was wondering if there is any way to check the harness to see if its in good condition or does any thing need to be replaced?


and is the any thing else i should make a priority while the car is in this shape(disassembled) as far as wiring /electronics, fuses or whatever

 

To check out every single wire with a meter would probably be a waste of time

Just kind of look over the harness, if you have any cut/exposed wires - fix them, any broken connectors - fix or replace them.

 

most of the harnesses/plugs and wires look good until i got to the plug that comes out of the tank(fuel sending unit) that has three wires all of them had been stripped behind the plug but the grey one had a wire wrapped around it and ran to the fuse panel wrapped around a fuse and inserted in the panel. how do i fix this

 

If it ain't broke then don't fix it.

But for the stripped/bare wires to the fuel pump, just find out how it was stock and replace the wire with the same gauge wire. It's really straight forward.
