Trailer hitch -- Does the 4 pin trailer wiring come with the wiring hot?

[Dperry285]

Does the 4 pin trailer wiring come with the wiring hot, I have a factory hitch, I know gm vehicles used to come from the factory with the trailer wiring unpowered, they put the fuse in a spare slot in the fuse box that you had to move to the hitch slot

22 OBX here and my factory hitch came with power at the 4 pin.

Hot as a pancake. Ready to tow, no waiting.

Maybe stating the obvious, but the wiring is "hot", but only for brake/signal lights. If you wanted to to add 12V power + brakes you would need to convert to 7 pin and make the other necessary changes (wire to battery for power. +brake controller, etc.)

I doubt however that a seven pin would ever be used on a BS, as that would indicate a heavy trailer or camper, as the hot lead in a seven pin is usually for electric brakes on the trailer or powering a fridge (in a camper).

7-pin will have separate pins for both trailer brakes and charging. Cheers!

My teardrop trailer uses a 7 pin connector, which I tow with my BS Badlands. I had to install a 4 --> 7 pin adapter to connect. I don't have it wired for power or brakes though. Some day I'd like to wire up for 12v power, but I don't need brakes.

Correct, but if converting from 4 to 7 pin without also wiring the 12v power to the battery or installing a brake controller, you will only get Tail/Running Lights, Turn Signals/Brake lights through the plug. That is how mine is set up since my trailer has a 7 pin connector, but I don't need brakes and can get by without charging from the vehicle for the time being.

You are correct. I just posted the diagram so others not familiar with normal wiring for a 7=pin connector would know. Cheers!

Thanks for that! I had to figure all of this out a few months ago when I found out the trailer I was buying had a 7 pin connector and I only had the stock 4 pin on the vehicle. Hopefully that diagram helps others in the same situation!
