im swapping a 95 xj 4wd drivetrain into my 90 2wd xj. the problem im having is that the np231 transfer case has a wiring harness on it ( from the '95) and the '90 xj wiring harness has the plugs for the tranny, but no plug for the t-case. what do these wire control, and how can i fix my problem? any input is appreciated.
