Wiring Harness Restoration Options

[bkrantz]

I have a bunch of questions about restoring the main and engine harnesses.

Any material or process to restore flexibility in the wire insulation?

Same for the original outer tubing?

For breaks in wires and large holes in the insulation, I think the best solution (short of running a complete new wire) is to solder-splice the break, and cover it with heat-shrink tubing--yes?

Any good way to seal small holes and cracks in insultation?

When replacing missing or broken spade connectors, crimp only or crimp and solder?

Thanks for all the replies. I do appreciate the wisdom gained from many years.

I am still committed (and maybe naively optimistic) about repairing the main harness. There are some real trouble spots, and more minor problems. Since I am not in a hurry, I am contemplating running complete lengths of new wire where I can trace a problem wire from end to end, since I have to untape and retape much of it anyway.

And I plan to warm up on the alternator harness, even though that is a relative bargain to replace completely.

I need to look at the engine harness more carefully (next on my list). My impression so far is that the wiring and connectors are in pretty good shape. The boots are trash, and the outer housing looks ugly.
