So, I was poking around the engine bay and found a single wire not connected to anything. It is coming off the harness at the front clip where the headlight wiring is on driver side. It has a weather boot and the wire is pink and white.

Any ideas? Thanks.

Well, that would explain why the front pulls to the right when I apply the brakes. Where exactly does it plug in at?

Thx!

Edit: I got it!

That will have no effect on why it pulls. There is a brake or alignment issue causing that.

Oh, bummer. It seemed to have lessened the severity of the pull.

That wire turns the brake warning lamp on when the spool in the proportining valve travels too far one way or another in the event of a brake failure.
