Thanks, Charlie.
So I went to salvage and pulled two harnesses for the hatch door. One had been repaired - fairly well - and the other was near pristine with no sign of impending doom.
Problem is the white connector which goes behind the headliner is completely different on my truck.
Mine: 4 wires
Salvaged (both ones): six wires, different colors and bigger connector.
The connectors inside the hatch door are a match.
Guess I will just have to repair the original one. Shouldn't be hard now that it's out and I can just work it on the bench instead of standing on my head in the back of the truck.
Disappointed I can't use the one in perfect condition with no splices or cracks.
