Anybody know what's inside the wire that's circled? Comes from under ecu and runs under battery. Wondering If the flat bits are cut on inside.

The only corrosion I can find on the entire vehicle is above the bcm. Not sure what that wire or plug controls.

No, I've had the carpet up and no signs of water.

Indicators, heaters, windows, rear door and wing mirrors aren't working. I've checked all modules, relays and fuses. I've had an electrician plug it in and the only thing not sending or receiving power was in the passenger rear door module. I've now changed the module and it works and locks door but hasn't fixed other problems. Anyone have any ideas on what else it could be?
