Activating 12 Volt Circuit of 7-Way on Hummer H2

Question:

I have a 2008 hummer H2 SUT and the center pin has no power. I took it to my mechanic to see if there was a fuse or something and he says there’s no connection lead on that center pin. I have a trailer with a winch and the winch won’t work . But I hook it up to my wife’s 2017 Ford explorer and it works perfect and it also work perfectly with my friends 2022 4Runner. I was wondering if there’s an adapter or something that will work.

If your 2008 Hummer H2 does not have power to the 12 volt on your 7-way you can activate it yourself. Just run # 10-1-1 wire from the positive post of your battery through circuit breaker # 9510 to the 1 o'clock pin on your trailer plug.
