I'm getting ready to put my revamped headliner back in my '87 4-cl / 4-speed (base), and I am going to install an overhead dome light. I was just going to do my own wiring job and then I encountered a mystery wire. I'm wondering if anyone knows it's purpose. It is coming off of (or at least it is sprouting from) the wiring harness for the driver's side courtesy lights (are they called "courtesy lights" or do they have a different name?). I'm colorblind, so I'm not always great with colors. The wire is striped. I'm thinking it is black and white, based on the Haynes manual I have. The manual indicates this is for the cargo lamp. Do you all know if this is indeed for the cargo lamp? If it is, I won't touch it, as that seems like something I might want to add one day. Or is it possible that this is for an optional overhead dome light? I probably should have looked at my wiring diagram before starting this post, as I'm starting to think I just answered my own question. Then again, I've been wrong plenty in my life. Heh. So what do you all think? Including pics for reference. If it is for the cargo light, I'm glad to know it. I didn't even realize that was a thing and I can see how useful it would be. I have a camper shell and a dog. It would be great to be able to run something to the camper and be able to check on Lima when it's dark out (among many other applications).

Definitely worth replacing the sockets/harnesses on each of the front turn signals. This resolved my always-on headlight indicators (always on when the headlights are on).

Dropping in 13 years later to say that after having the always-on turn-signal indicators in my 1987 MJ for many years, I finally got around to swapping out the two front turn signal sockets/harnesses and that fixed the problem. The ground on one of the old ones was very clearly rusted all the way through (the rust had eaten all the way through and the prong was loose/broken). I checked the indicators after changing each harness and I could see that it resolved the always-on issue one at a time. I used these ones by Doorman. The Autozone computer system said it wouldn't fit my vehicle, but they did. However, on the driver's side, it did require a little bit of force to get the headlamp housing to fit back into place and lineup with the screw fastener holes. I'm going to make a TikTok about it.

Just dropping by to say that I had the same issue recently, and it was the "trans" fuse. Now... as to why that fuse keeps blowing? Only the fickle Jeep gods and their gremlin minions know why.

Final question. Are you happy you took the time to put AC in your 2.5L? I see a lot of folks saying I might as well just upgrade to the 4.0, but I'm a bit invested in my 2.5 at this point — and it only has 115,000 miles on it.

Thanks a bunch. I think I'm beginning to wrap my head around this. One more clarification question: Are you saying that if I find a 4.2L AMC I6 I might also find a compatible AC bracket? I'm scanning the Wikipedia entry for the 4.2L right now. Looks like it was used in a variety of cars for many decades. I'm assuming that if the bracket from a 4.2L is compatible that it wouldn't be compatible in every single vehicle that the 4.2L ever appeared in — that there are variations.

Thanks @eaglescout526. Forgive my ignorance here, but I have some followup questions: 1) Is this bracket a two-part thing? If I find one, will all the pieces most likely be together, or might I have to piece it together from two separate vehicles? 2) I saw on a different thread that @Jeep Driver had a photo of a super clean and polished 2.5 L with the AC bracket (see Jeep Driver's photo below for reference). Again, I'm new to this world, but all the parts on that engine look ridiculously clean. Did you somehow get that bracket fabricated, Jeep Driver? Is that something that is possible? We live in a world of 3D printing, after all... Please, explain this to me as if I were a child, because in this instance I basically am.

Hello Everyone. Can someone post a picture of what an AC/Alternator bracket for a 1987 2.5L looks like? Alternatively, can someone let me know if I'm on the right track in my search (photos below). I understand they are hard to come by, but they are REALLY hard to source when I can't even figure out what one is supposed to look like. I've found many brackets in junk yards all over the Western U.S., but the mechanic who is helping me with this project keeps saying they aren't quite right (because they either came off of an XJ or they came off of a 4.0 MJ or some other complication). I am going to attach images of some of the brackets that I've found in my search. Perhaps one of these is actually the right one and my mechanic is mistaken? Help!
