Our 2009 Silverado 2500HD came without the 12v fuse installed and the wiring not hooked up for charging the trailer battery while the truck is running. How do we install this to function? Thanks!

You will need to make a couple of connections under the hood to complete the trailer wiring package on your vehicle (see link). The ring terminal for the 12-volt power lead for the 7-way trailer connector is located to the left of the power distribution box, and is taped to a wire harness under the power brake booster. You are looking for a red wire with a ring terminal on the end. This wire needs to be connected to the right side stud at the front of the power distribution box.
While you are under the hood you should probably go ahead and connect the brake controller power wire to the left side stud also. This wire is located at the right side of the power distribution box next to the fender and will also have a ring terminal on the end.
If you need to install fuses after the connections are made look under the cover for the power distribution box. There is a diagram that will tell you where to install the fuses and what location they belong in.
