Review on Enhanced GM Electronic Brake Control Wiring Harness - Genuine Parts #15776487 by Shane Schobinger

Installed on a 2005 Pontiac Grand Prix Base 3.8L V6. There were problems with ABS/traction control. This seems to be a common problem with all GM W bodies. This belt is the right length. Easy to install if you remove the mounting clips before installation, too many bottlenecks to get through the mounting clip gap. Make it easy, stick them back on after installation, just mark their position and orientation on the hanger (you can re-stick the old clips before removing the new ones for comparison). Compare the old and new to make sure you have the same side length that goes to the same sensor as the old seat belt, otherwise you'll get it and find that one side is too short. Installation took about 2 hours as I struggled with the mounting clips for a while before deciding to remove them. Stick them on after installation. You will need to cut the center rubber grommet where the wire harness exits on the right and left side of the vehicle, make a clean, straight cut, and reattach it after installation. In fact, this is a rubber boot that keeps the wires from rubbing against the frame. Some descriptions of this AC Delco part refer to it as a trailer brake harness, however this is the correct harness for the ABS system. The problem has been solved. Ready.
