Product details

This 13-pin electrical kit, made by TowTec, is suitable for the GMC SIERRA 2500 HD Crew Cab Pickup . The 13 pin Top Tronic wiring kit will increase the frequency of the turn light indicator when a trailer light is not working.

If available you can turn off parking assistance of your GMC SIERRA 2500 HD Crew Cab Pickup with a button on your dashboard. Vehicle-specific plugs are not included in this electrical kit. It is delivered with detailed assembly instructions. It's not required to connect each cable to a trailer socket. A socket is already connected with this kit.

It is possible to extend pin 9 of the trailer socket to steady plus (to power electric items in the trailer) or pin 9 to steady plus and pin 10 to charge (e.g. a separate battery in the trailer). By adding the extension set 128476 you can combine charging and steady plus.
