Dogs tore up my harness trying to kill some kind of critter and I have wore myself out trying to piece it back together for everything to work right. It's just not happening. Chevrolet doesn't carry them anymore, can't find them in any wrecking yard and can't seem to find one online. Surely someone still has some of these things. I'm about to set this damned thing on fire. Lol

 

My best suggestion would be to try to find the harness label - they all have them, at least at one time. Then you can do a part number search for a new old stock part. There are likely tons of different part numbers for that harness, different beds/cabs options, etc.

Or if you are willing to remove the harness completely for repair, PM me and we can talk about some options.

 

why models years have you searched for at the wreckers. get the dealer to tell you the range of model year that would cross over. a 07 classic is just a carry over 2006

 

This might work for you.
