So here is one for you guys...

2005 Express 3500 2WD 8cyl 6L (JL4) with ACTIVE BRAKE CONTROL

I get an ABS light pop up and I start digging the web for possibilities. Start inspecting around the EBCM (electronic brake control module) and notice right off the bat a seriously damaged EBCM connector. The male side. It looks like someone tried to pry this off before. The actual EBCM female side looks fine. Anyone know part #, cost, source?

Broken male EBCM connector housing.

Hey that looks just like mine. Smashed. It's mounted on the frame, right? Where it's vulnerable to flying debris. Dumb design if you ask me.

Luckily I don't get an ABS light, but I inquired with GM about fixing it. They told me I would have to replace the entire harness. If I were you, I would try to repair it. That or find one at the junkyard.
