That's not the case and the easiest way to fix your car is to swap/fix the wiring on your car.


do you know if the m103 came out of a w124 (different engine mount arms)


do you know if the transmission will bolt straight up?


cis ecu wiring and ezl wiring would have to be custom unless you have a donor (Do you have these modules/plugs ?)


custom exhaust?


different fuel lines?


as you see it's a massive project
