Need 87 Bulkhead Pinout

Replacing the 4.2 with an 89 XJ 4.0. I have found the pinout for the 89 XJ, but can't find info for my 87 YJ. Anyone willing to share?

Your not really gaining anything by swapping out the 258 for an 89 4.0. If your 258 is good, I would swap on a 91 and newer 4.0 head and get a good carb. The FI system on an 89 isn't the best in the world. Actually, a 258 with a 4.0 head produces better torque at a lower rpm. I wouldn't trade my 258 for a 4.0. I swapped on a 4.0 head, holley TA 470 4 barrel, offy intake, cam and so on and that thing screams. If your 258 isn't any good, then it makes sense.

Simply put....I hate the carb and the FI engine didn't cost me anything.

That engine isn't MPFI, I personally would hold out for the HO 4.O system.

Even though this has nothing to do with my original question...please enlighten me on your claim that the 89 4.0 Renix motor isn't a MPFI system


Come on guys...I don't need someone to tell me which engine you feel is better and what I should and shouldn't do if I were you...I'm just looking for a pinout/diagram so I can continue onto installing this engine and getting it running.

Well after weeks of searching and coming up empty handed. I got a temporary log-in to alldatapro.com and searched for an hour and thought I came up blank again. They don't show any bulkhead information for 87 and 88. So I took a stab in the dark and saved images of an 86 CJ and an 89 YJ. Came home and figured I would compare to see if either was anywhere close. Come to find out the 89, which I was specifically told was different, was identical to what I had! Yeah!
So here's the image for any future people searching for this information.
