i have a guy wanting to swap his e- locked third for my open third. Is the shaft and third the only thing i have to swap? as far as wiring what does it take to run this thing? for my elocker in my chevy alls it took was a constant twelve volt lead and a switch is it the same with this? i have read about swapping harness and ecu's and all that jazz but that seem like alot of work i would rather avoid. Also if i decided to run one of these in my 40 would it be the same wiring set-up?
