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?

digi key connectors just like original with your special crimp tool, no solder. I replaced all the tube that covered the wires. Not an easy job but nothing will bring the old plastic back to life. I purchased the loom tube from McMaster Carr. It has printing on it that comes off quick with lacquer thinner.
Solder breaks and extensions then heat shrink tube. It will all be covered by the loom tube. If you don't know exactly how long a piece should be where the end is missing make it way to long and add the connector when back in the car.
I heat shrink connectors that carry current just in case something should bump it.
Have fun.
