Question:
I have a 2002 silverado and it doesn’t come with a towing package. I’ve located the junction box by the pedals and understand how to connect the brake controller to that. I’m stuck on how to bring the blue and red wires to the back of my truck in order to connect it to the 7 pin adapter. I don’t understand what to do with those red and blue wires by the fuse box and how to get those connections to the back.

Check out steps D through F on this link I attached to this page. Basically the red wire goes to a post on the relay box and the blue wire gets connected to double bonded wire like part # 10-2-1 and ran back to the 7-way.
