I’ve searched but can’t get an answer.. so I took a 98 XJ that had and auto trans and swapped into my 89 that I’m running a NV3550 in. I used my 89 flywheel/tone wheel and I’m having problems with it running and it won’t rev up. Does anyone know if it’s because the 3 wire crank sensor is not reading the 89 flywheel correctly? Or does it not matter? Thanks

Runs for about 1min or so give or take. Yes complete swap dash harness and engine harness running the XJ tank and pump

So I swapped a 98 XJ engine into my 89. Complete harness and computer. The lower end was junk in the donor so swapped head to my 89 block. Long story short.. engine will run but will die/stall. Fires right back up. Same thing. Can’t accelerate. Have replaced crank sensor, pickup sensor, injectors, fuel pump, throttle position sensor, MAF sensor, idle air sensor, new plugs, new o2 sensors but downstream is not in yet need to weld in bung. etc.. what I do notice is tach jumps around when it does start up? I’m about 95% sure timing is on. But going to double check tonight. Any help would be great or if anyone has experienced this before please message me thanks again

I’m doing a 97+ swap wondering if anyone has a pinout for the grey plug for the rear lighting/fuel for a 98 XJ. Thanks

Did you do your dash? Wondering how it’s holds up in the hot sun? Thanks

Thanks I’ll take a look at it

I’m working on swapping motor and dash and harness from a 98 XJ it was an auto 4x4. My question is will it all work on my MJ with a manual trans? Guys have said no I need a different pcm? Wondering if I’m screwed

I’m parting out a 98 XJ so let me know

I have a couple

Cruiser54. Thank you. I seen that on another site but was just asking to double check. More work but will be worth it!

Looking for some help. Does anyone know if a 98 head from an XJ will work on the block of my 89 MJ? Was in process of doing 98 swap and found the block of the 98 is junk. Just looking for options. Thought I could swap head, distributor, intake and so on to my 89? Thanks for any help

Sweet just added myself pretty awesome site
