I searched the archives but didn't find anything regarding my problem. I just purchased a late in the year 2007 new body style Silverado 2500. I asked the parts guy at the dealership for a cable to connect my Prodigy brake controller to the fuse box in the truck. He said I would be better off contacting an RV dealership. I contacted my RV dealership and they said Chevy changed things late 2007 and I would be better off going to the dealership parts guy. I can't be the first one with this problem. Any suggestions from someone who's been through this already is appreciated.
