yes i am sure the wiring will be the hardest part, what is the best way to do it, pull it all and re-wire or, leave as much as possible on the frame/engine? my plan is to just pull everything i can into the engine compartment and lay it on the motor, then pull the cab off, pressure wash everthing, and then put the new cab on and then put all the wires back into the spots, so far i have thought of brake lines, rear heater, heater, fuel lines, and wiring anthing else i need to remove? thanks
