I bought a wiring harness from Brothers Trucks, and its from american autowire. My problem is this. I’m trying to wire the reverse lights, but I dont have any loose wires to make a connection under the steering column. The instructions that came with the kit dont even list the wiring for the reverse lights. I have the original harness and I have used a few of the connections to attach wires as I’ve needed. I have the plug for the reverse lights, but I dont know where or which wires to cut and attach the plug to in order to connect it to the steering column.

My next question concerns the brake warning? light. This wire comes out of the bottom of the brake fluid resevoir. Do I need to utilize this plug/wire in order for the brake lights to work, or is this simply the brake warning wire that tells you when there is an isssue witht the brake system? I have the two tan wires on the instrument cluster #2 pin that arent connected to anything.

Thanks for any help, guys.
