Re: WHAT IS THIS, AND WHAT DOES IT DO ???
You didn't give much of a hint, like what car/model, where you found it etc...
When checking the partnumber 12020004 that appears on it on gmpartsdirect.com, it comes up with a single hit:
Electrical - Abs components - Module - Malfunction indicator
W/traction control - 1997-99 1997 - 1999
Don't know how accurate that is though..
