Thanks for the reply. I verified that I DO need the RZY harness because I'm missing pins #9 and #11 on my body harness. What I am interested in most is the powerfold function for the meantime. From my understanding the rzy harness only adds circuits to the lighting functions. I wonder if the fact yours is a 1500 differs in application to mine aside from considering the exhaust brake and ambient sensor on passenger side. Does yours have memory seats? Mine does not have memory seats. Just want to confirm if buying dqs and powerfold switch will be enough to give me powerfold, power adjust and heat.
I know eventually I will need to install RZY jumper harness and additional door harnesses to get full light features.
Here is a brief section I copied from a bulleting or instructions from gm ".......This upgrade is ONLY for the models listed below, and is NOT recommended on 2015 models without RPO AVF or 2014 models, due to electrical differences in the fuse protection."
Then further down it states this "
Trucks built at Flint Assembly, 11th VIN position “F”
Note: DQS Camper Mirrors are NOT RECOMMENDED for upgrading NON-FLINT BUILT TRUCKS"
Thus confusing me more because my truck is a 2105 model without rpo AVF but WAS built in Flint, MI 04/14
