Im repairing connectors on my harness. I have Amazon depin tools and of course I broke the smaller one. Anyone know of a better depin tool set?

I have a larger connector (1J0-973-752) I depined to repair the wire jacket. Connector is good. Copper is good. No/few broken strands. Pins are good. I had to go wayyy back to get to good jacket but I was just going to repair the jacket and put it back together. I forgot to take a photo. Anyone know which pin is ground and which is power? Connector marked 1 and 2. Is 1 power and 2 ground?




My knock sensor wires are crispy and taping up jacket that small is not gunna fly. Im going to have to replace the wire and crimp on new pins. Anyone know the wire gauge?



My coolant temp sensor is totally shot and mostly missing. Know the part number?



Both sides of my AC compressor connector are missing. Last guy just spliced them together. I would prefer to put at least A connector back even if not the right connector. Is the female/compressor side of that connector even available?
