WM Headlight switch connector pinout and connector info.

Had the need to search for a new headlight switch connector for a 11-13 WM PPV tonight. Here is the relevant info if anyone ever gets a PPV with the connector cut off.

Connector information from GM:

The part 15775804 number is a good GM part number for a connector but I am not sure if it is just a connector body or a pigtail. It does not appear on ACDelcos catalog of pigtails so I am skeptical it is a pigtail. Cannot find a photo of one.

However the connector body and terminals are TE/AMP products. DigiKey has them both in small quantities.

And I have been suggesting to guys to get a barrel crimping tool to make up these connectors. I use a ratcheting type of barrel crimp tool but that can be difficult for a beginner as you can't back out once you start crimping. These are a standard set of barrel crimp pliers and although you have to do 2 crimps for each wire (one for the wire one for the insulation) that's OK as we are not doing production work here! We can take our time doing them.
