Hello, I swapped the transfer case out of my 92 xj with one out of a 93. Both are 231's. Both were exactly the same with the exception of the one plug on the tail end of the transfer case that sets on top of the housing where the rear driveshaft is. I can't remember right off which was which but one was for a 2 prong set up and the other was a 3 prong set up. I did not notice this until after it was in and that was the only thing left to hook up as far as wires go anyway. What's the easiest was to fix this issue? Thanks in advance!
