I had a really quick question.

There are a series of plugs between the hydrolic reservoir and the ABS setup. I think there are three or four round plugs with purple wires, and a square black plug with a black wire. The black plug runs in between the radiator and the core support. I need to know what the black plug connects to because it got caught into the fan and pulled away from where it goes. I know as of now, the alarm for the hood works, and the electric fan works. There isn't anything else I can think of it going to. If anyone has an idea of what this wire might goto, please give me a hand.

It's on a 99.5 A4 1.8t Quattro

Thanks alot
