carnuck Posted March 8, 2012 Share Posted March 8, 2012 Anyone have the firewall pinouts for an '87 MJ (4.0L std 2wd) and a '90 XJ (4.0L AW4 4x4). I swapped my wiring and I'm about to hook up my battery and I hope I'm not about to smoke my wiring. Link to comment Share on other sites More sharing options...
Harley Posted March 8, 2012 Share Posted March 8, 2012 Eh fire it up and hope for the best. But just in case, have a cam ready cause if it smokes we wanna see it on youtube! Link to comment Share on other sites More sharing options...
knever3 Posted March 8, 2012 Share Posted March 8, 2012 That's the exact swap I did. My '90 donor had A/C too, everything works fine. Link to comment Share on other sites More sharing options...
