What is this? I have an extra wire on my ECU plug for this and have no idea what it is. It connects to the Thermister, but that doesn't help as I don't what that means either

If anyone could help me, I would love you forever... or at least about 5 minutes

it is used to switch off the AC under heavy engine load (i.e. WOT) IIRC. It's used to switch it off under some condition.. I think its WOT. Basicly it fakes the AC system into acting like it's already too cold so it shuts off.
