Found a harness on the net and it was in good condition and the price was right , my old harness not so much.
I’m in the process of labeling all the connections and removing the harness tape. Holding everything together with zap straps .

There are a few wires that appear to be stuck together by heat and some that have been bared probably from being removed through the firewall (scraped) .

The colour code wiring is relatively the same colours as the original

Question

On the bare wires should I use heat shrink tubing and on the wires that where cut should I solder the same colour coded wire from the old harness then shrink tube them?

I’ll post pics tonight

Rather than long runs of wire with heat shrink on it; I would splice in sections from the old harness and just put heat shrink on the joints.

Otherwise, your plan sounds good.

For joining wires like that, I use a variation of the "Western Union" splice rather than crimp-on butt connectors. Be sure to slide a suitable length of heat shrink onto one of the wires first, though, and keep it far enough away so it's not affected by the heat of soldering.

You should have asked me, have some better than that. I replace rather than worry about wires melting together again.

Thanks. The harness other then 3 wires seams pretty good still thanks though

For 5 bucks I laminated a schematic- way easier then looking at the iPhone

Brian, get a 12 inch long 4 X 4 to solder the wires on. Dip in flux and twist together, let the wire melt the solder not the tip.
Pushing on the wire on the wood will make it go much faster.
I'll get to our project shortly.
