It did but I was told it is bad. I don't know what "nad" means. Hard to confirm without the goods installed. I can still try to get a 1995 computer from a junk yard.

So instead of being lazy, I pulled the wiring harness out, and I counted six fuel injector connectors. Apparently the harness came with the motor after asking the previous owner again.

The number on mine is 508MX02. This helps and is online with the harness you mentioned.

I reached out to the previous owner. Turns out the wiring harness is for the 2.5. It's not in the Jeep. What year would you recommend I take the harness from?

It's a 1987. I do have the wiring. Not 100% sure if it's for the 4.0 I was given with the truck, or the 2.5 that WAS in the truck originally. I believe the harness is for the 4.0. Haven't gotten far enough yet to go down that rabbit hole.

Of course after posting, I saw this post: I'd still love everyone's input.

So, I'm new to this site, and MJs but not new to Jeeps. I've had several wranglers (3 TJ, 2 JK, and 1 XJ) I've wanted an MJ for a long time and finally came into one. I retired from the Army last year and my wife got this guy for me from a neighbor. It was the former owner's project Jeep, so not much is actually installed. If you could build an MJ from scratch (which I kind of am), keeping as many stock Jeep (don't care what model, just don't want overpowered aftermarket upgrades) parts as possible. To be used as a street queen with minor off-roading (body can't handle it anymore). What would you consider the best to install, from what model Jeeps and why? For instance, I pulled an almost complete radiator / cooling system from a 2001 XJ. Only thing I didn't think to grab as the cross brace on top of the radiator that holds in. I currently have: 4.0 I6 Manual transmission Transfer Case Cooling system (with additional electric fan) Miscellaneous interior / exterior parts. Things I would like: The stance (mentioned below) 4-wheel disc brakes Mostly stock looking interior, with bench seat Most stock looking exterior Automatic but not required I love the stance it currently has (without the motor though). The front is a Dana30, the rear, I'm not sure but the previous owner said he put it in just to be able to move the Jeep. I'll need a new rear diff. I'm not opposed to that being another brand (Ford 8.8 for instance). I'm not the best at writing up builds but I can try, if anyone is interested.
