OK, maybe I'm doing something wrong, I sure hope so.

My RWAL light has been on for a few days now. The only black wire I found behind my glove box ends in a one pin connector. If I try and ground out that pin, nothing happens. Is this the right wire?

 

The "brake" light comes on for the park brake, proportioning valve, vacuum sensor, and the RWAL. The dodge RWAL was a real POS. It doesn't store codes alot of the time it should and has a problem turning on the light if the rear wheels lock up for a split second during hard braking.

I had a water intrusion problem with the vacuum sensor connector this spring in heavy rain storms that would turn the light on as well.
