I have a 67 ford f-250 the wiring was bad fixed everything except I need to hook the green and yellow wires somehow up to the switch on the brake pedal. I have several different wiring diagrams that none of them match exactly. 1967 F model, 1968 F model, 68 E model, 67 E model. I would suspect that F model should be F series pick up E is econoline. My main question is the turn signals going backwards from the tail lights to the cab should be a green wire and a yellow wire they go to the directional switch. I need to hook up the switch on the pedal but I dont have any available wires left. None of the diagrams show the pedal switch. The brake lights need that switch to know when the brakes are activated.I have other issues to but this will get me going again.
