Big Diesel Posted October 29, 2013 Share Posted October 29, 2013 Hello guys I own a shop and I have been really trying to help out one of my customers , her 89 jeep comanche has major sentimental value to her but the leaky brake master destroyed the fuse box and ive been looking for awhile, the part number from Chrysler is no longer available. So I'm in a situation and i need one asap, so any help would be much appreciated you can pm me or call / text 740-818-1558 thanks so much Link to comment Share on other sites More sharing options...
jimoshel Posted October 29, 2013 Share Posted October 29, 2013 How much difference is there between a '87-'88 fuse box dash harness, of which I have many and a '90, of which i don't have any? Don't text. Fingers to big for them keyboards. Link to comment Share on other sites More sharing options...
HOrnbrod Posted October 30, 2013 Share Posted October 30, 2013 Jim, the parts manuals say the same fuse panel (p/n J4179458) was used in all 86-93 XJ/MJ models. Link to comment Share on other sites More sharing options...
carnuck Posted November 1, 2013 Share Posted November 1, 2013 The '87 to '90 firewall connector is the same (I have a '90 underhood harness on my '87 for the AW4 swap) I think I still have the '89 MJ underdash harness from the rig I parted.
