The wired looks like it got pulled any part # for the harness?

 

No but I believe it's just a two wire weather connection an parts house should have a pigtail you can splice in. These are sensitive so use shrink tube to cover your solder connections

 

GMpartsdirect.com or any of the GM parts sites should lead you to a part number. However, be prepared for sticker shock! That type of pigtail usually is in the $40-$80 range.

Which side is messed up? If it's the wheel side you would be better off replacing the hub, They can be had for around $40 on eBay.
