How much will this cost me? A couple bucks a foot for the cord and an hour or so of time.
Replacing the cord is not a hard job for anyone with a few screwdrivers and the knowledge of how to use them. You can buy the 7 conductor cord at most auto parts stores. Remove the plug end from the old cord and attach to the new piece of cord. Hook up the wires as they are connected into the trailer wiring and you are good to go. Just measure the length of cord you need before you buy it. I didn't follow this advice and bought a piece of cord a few inches too short, which means I waisted 6' of cord.
