Quick question just seeing if anyone has put a aftermarket headunit in a 13+ with factory trailer brake? Does the trailer brake controller still work? And how do you change from light to heavy electric ect? Or do you just leave it on one and move on?
Edit: Ive done many aftermarket systems on dodges and I know they require the interface module or what ever you call it.
