the Portion of the 3800 Harnesses, where there is a Plug that goes to the coils and the Crank sender and cam sensor, Is That part of the Harness the same(interchangeable) between the SC and the NA ? Thanks
All years seem to be the same as long as they used the same 8 pin connector. That connector changed to a purple insert in about 2005. Look for cars that don't have the motor mount going from the engine through the belts and to the frame. The mount gets in the way of unplugging the connectors. The radiator hose will keep you from getting the wiring out so you have to remove the hose. Just cutting it short won't help. Many times the ground lug stud spins so be ready to just cut it and replace it if that happens.
I got 2 this afternoon. you are right about the hose being in the way. fortunately the cars were up in the air with the wheels off and Balancers missing so the crank & cam sensors came right off. I can't believe there were 7 3800SC cars in there at one time.
