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?

Yes you can get new connectors, sleeving materials are available, not exactly like stock, some better , some not so much. What Jeff is getting at is that with a wiring harness, you can be chasing problems that are intermittent on an old harness unless you replace all the wires. They may look good, but unless you take the old sheathing off and replace it you can't tell. This will require most of the connectors to be removed from the wire to re run them back into sheathing. There are multiple "branches" so order of operations is important. Also you do want to make sure you "tie off" the ends at the circuit board side.
