Can Factory 7-Way on GM Truck Power Electric Winch

Question:

I have 2 GM trucks with the factory 7-pin trailer connectors. I was wondering if the connectors / wiring could carry the load of a 2500 - 3500# rated electric winch attached to my receiver.

The 12V circuit on the factory 7-Way connectors for your GM trucks won't have enough power to operate your winch, especially when it is under load. The problem isn't just the circuit's rating but also the wire gauge that is used. Powering an electric winch will require much thicker gauge wires to prevent them from being damaged.

To wire up your winch I instead recommend using a winch wiring kit like the Bulldog # BDW20207. This includes 24 feet of 1 gauge wiring along with quick connects and a vehicle side dust cover. I have attached an installation video that you can check out as well so you can see exactly how it works. I have included a great article on this subject that you might also find helpful.
