I messed up here and need a little help, I was replacing the brake lights and signals ect. Well during this process I cut it off somewhere. There's no wiring coming from the cab to the brake lights so I can't find where to splice in some new wiring, im all iost I looked at some diagrams but I can't find where anything leads, any help is appreciated

 

Start at the easiest thing, the brake light switch under dash and mounted to a bracket next to the brake pedal arm. See if you have 12 volts to it. Key does not need to be on. If no voltage, of course check the fuse first. You can run a jumper wire from the batt + in turn to each of the wires on the brake light switch to continue testing the circuit but you need to fix the issue with no feed to the switch.
If you have voltage to one wire, good, as it should be. Now depress the brake pedal and the other wire should also light up. If not, replace brake light switch. If the other wire does light up, trace it to the steering column. It comes out of there to the tail lights. Your wiring diagram should help you at this point.
To trace the wires, start at the back of the truck and trace them to the front, you will see where they go into a bundle or into the cab near the steering column area.

 

So far I found a black and blue stripe wire mated with a green and yellow strip wire in both door jams do these have anything to do with the tail and brake lights?
