2005 GMC Sierra. Purchased new in 06.'
After several years the airbag light would go on and off when the passenger seat was moved forward or back. Now the light is on constantly. I ran the airbag code and it said the issue was under the passenger seat. Quick look and I found this:


So it looks like several wires broke off of the connector. I did some searching on the site but didn't come up with a fix for this exact issue. Can a new harness be purchased or ?
Thanks for any info.

 

Should be able to buy a new harness whether from dealer or a junkyard, but you need to figure out why that happened, so you can prevent it in the future! You may be able to get the connectors, a wiring diagram or a connector end view; and repin the wires back into the connector.

 

I was just curious if anyone else had run into this issue previously as I couldn't find much searching the web. I did read that these wires can get caught in the seat track and be severed. Looks like that may be what happened here.
Regardless, I called a dealer today to get the part number, price and availability for a new harness. They want $151 for a new one. I did some searching online and the only other place I could find the harness under that part number was GM Wholesale Direct and E-Bay. GM Wholesale Direct was cheaper, even after shipping, at $94. Ordered one up, the part number for anyone interested is: 88978225
