I'm trying to get 12vlt power out of the 7-way plug. the blade at the 1 o'clock position should have constant power for battery charging in trailers.
I have no power and can't find anything in the fuse panels or owners manual on how to do this. I had a 2002 2500 HD and it had power there.
I checked the back of the plug, all the wires are in place, just can't follow them to the front of the vehicle.
