HI i am in the middle of doing a mpi swap like the title said. I have a couple questions.
1. The + cable on the battery what does it connect too?
The PDC, starter, and alternator???
2. The return line on the fuel rail is the connection thats connected to the regulator right ??
3. On the bulkhead connector i was going to move the pins around on the inside to connect to the right ones from the engine harness is that the only wiring i need to modify on my old harness on the yj???
Also when looking at it from the front the right side on the yj harness is for lights, horn, etc.. The right side on the cherokee harness do i need to do anything with it or can i take it out of the harness?????
I have a engine harness from a 93 cherokee, have the 93 alternator. Going onto my 89 YJ
thanks for the help
