So this wire comes off the temp sensor on the front left head to the "temperature unit" in the speedometer. It's a green and black wire and isn't damaged in any way.
Coming back out of the temperature unit is this pink wire, it travels back down into the harness and joins another pink wire in the harness here.
The other pink wire goes up to the water temp light here.
Further down the main harness the two pink wires connect to this plastic peice that looks similar to an inline fuse(not sure what it really is) and then becomes a green yellow wire.
The other side of the water temp light is the orange wire which I believe is hot.
I believe the short is happening where the green/yellow wire meets the plastic peice, then goes onto be the pink wire. I'm not sure what this plastic peice does or how to repair/replace it.
Also can someone explain to me what the "temperature unit" does and how it functions? To be clear this is the unit that's behind the speedometer, not the temperature switch on the head with the green/black wire coming off it. I suspect that works similarly to a thermostat and opens the switch and provides ground above a certain temperature right?
I was hoping to just replace the whole harness and to be done with this, but it's probably better that I understand what's going on here I guess...
