You should have not needed to change anything on the stock wiring harness for the body part (lights, radio , and such). The engine wiring is separate under the hood verses the lighting, accessories ( horn, washer). Now the engine harness does have the heater fan and A/C wiring in it. So now what did you change?
A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.
