Brake lights problems

1969 F100. Previous owner had backed over something and dented the roll pan and tore the rear wiring harness apart. The wires leading to both driving lights/ brake lights/backup lights are still there, but the plug that those wires plugged into is gone. I found which wires are hot when the rear running lights are on, then when truck is put into reverse, and then when the brake pedal is depressed. Can I just splice all that together to the existing tail light harness to make them work for now? In the picture I marked the hot wires for the brakes with a "B" , the running lights with an "R", and the backup lights with a "BA". Any pointers on how to make it work?

Yes you can splice the wires to reconnect them. That's what was done to add trailer lights. I would recommending soldering the connections and seal up with some shrink tubing. These wires are under size so they will not carry a lot of current, besides the voltage drop. I would use 16 ga wire if you need to extend them.
