Hello everyone. New member from Lillington, NC here. I have a question I hope someone can answer. Just bought an 2018 Silverado 4x4 with trailer package. Found a Z82 connector in glovebox with instructions where to plug it in. My question is what or where does the other end of this connector get hooked to? I have a factory installed trailer brake controller in dash and the trailer connections are installed in bumper. So what to do with the other end of this Z82 connector? Thanks, Devon.
