I just purchased a new 2007 GMC Savana 2500 cargo 6.0L with the towing package. I have been unable to get 12 volts B+ at he 7 wire connector that was tucked up in the frame rail at the rear of the vehicle. The user manual indicates that maxi fuse #50 in the underhood fuse box is for " Trailer" It is present and has power. Is there someting else I need to connect to enable auxilary power for the trailer?
