I know someone here works at a Chevy dealer, so heres the question. I looked on my truck and the part# for the license lamp harness is 15768809. I have heard the 3500s have a different harness which incorporates an additional connector into it for the center light bar. I checked my part number on GMPartsDirect and the cost is only $18.78 so I wouldnt imagine the 3500 harness being much more. If anyone can find me that number it would be greatly appreciated. If not I guess I'll make a trip to the dealer next week.

Thank you for your help.
