This is my first time posting in any forum so if it's the wrong place or anything, forgive me. Anyway, I own a 2014 GMC Sierra 1500 SLE. I had aftermarket step bars on it. I recently purchased a set of powered step bars from someone and was wondering if im going to have to purchase any additional wiring harness or mounting plates for these powered step bars to work, or if the electrical is already run on the truck already and it'll be an easy plug in and go. I'm thinking the plug in and go option isn't very likely. I have already taken my aftermarket step bars off and wanted to pose this question before continuing with this endeavor. The powered step bars I purchased are apparently off another GM or GMC Vehicle as they have a GM Part number on them already (GSM0C7). This may also just be the motor number for the step bars but it's all the info I currently have for them. Any info anyone else can provide would be much appreciated. Thanks alot.
