Hello,
I have a 2002 Sierra 2500 HD 4x4 crew cab w/ tow option. I tow a 5th wheel with it. 6.0 gas engine.
Under the hood I have 2 batteries yet at the 7 pin towing connector I have no 12v aux power. In the electrical box under the hood is supposed to be a 40 amp fuse for this connection but it appears that it was never a finished connection. No fuse and no circuit in the box for the fuse, just a provision for it.
Is it possible that this 12v aux to the 7 pin connector is wired another way? Makes no sense to have 2 batteries under the hood without providing power to something else. (no one ever said it has to make sense)
Thanks
