I was wondering if anyone had a good way to replace the worn away insulation on my wire harness with out cutting the wire and shrink tubing them. I was thinking of shrink tape but there are like several wires with the insulation missing.

You can get a can of Marine electrical insulating liquid, and apply several coats as needed.

yeah I was looking into liquid electical tape but wondered how many coats will it take and so on.

It is time consuming, only because you will need to let it to set up, or get mostly dry in between coats. Usually 3-4 coats is sufficient.

Are you saying the insulating wrap around the bundle of wires has deteriorated, or the actual insulation around the copper core of the wires has deteriorated?

If it's the latter, you need to get in there and replace the wiring as needed, else you risk having intermittent electrical problems at least- and at worst you could burn the car to the ground.

its the insulation on the actual wires it also went through the plastic conduit. anyway im on my 3-4th coat of liquid electrical tape and that seems to be working good ,a couple more coats and ill tape everything with 3m 333 and rebundle it all in a new plastic conduit and hope for the best.

Back in the late 70's and into the early 80's, Ford used a 'white' grease, it looked like lithium grease to me, inside of the main wire harness connections. This 'grease' would wick down the wire, and shrink the insulation exposing up to an 1" and a 1/2 of bare wire.

I offered this as a cheaper alternative, to the cut/shrink tube/splice repair. I have never seen, or heard of any problems using this. It does set up pretty hard over time, but it does not get brittle and break off. You have to cut it off with a knife.
