I bought it at a GMCMI event. My problem is that I didn't think about the fact that the wiring plug wasn't there. And I don't know what it came on to find out how to wire it. The 4 terminals are labeled A B C D. The part number on the end is 5048679. There are two ports. With one labeled outlet on a funnel shaped piece. Does the outlet port go to the brake booster?
