90PioSport99

Hey guys, I have transplanted the complete drivetrain and wiring harness/PCM from a 1996 XJ into my 1988 MJ. I have a verified good battery, and have power going to the lighting circuits, but there is no power going to the ignition switch. Thus far I have not joined the XJ front harness to the MJ rear harness as I’m just trying to get it to run. Does this sound like an ASD relay issue? Will the ASD still allow it to crank and supply power to the other circuits? I do know for a fact that this harness/pcm is good because it ran just fine in the donor vehicle. And all fuses in the underhood PDC are good. Thanks in advance for any ideas/help. -Collin

Hey I recognize it! Only because I'm the one that sold it to you :D Interior is looking great man! Can't wait for you to get it finished!

When repairing a buddy's Comanche we found that late 90's Ranger shackles are almost identical to Comanche. Definitely close enough to use. Available in stock (usually) at any parts store. If you're in a hurry.

Did you see my offer above?

I have one I'd go $20 shipped on. Alternatively, I have a 96+ manifold and ps bracket that would give you the new belt routing and tensioning if you'd rather go that route. I'd let the manifold go for shipping cost and charge $20 on the bracket (it would fit in the same box). Let me know if interested. Thanks, Collin

Still looking for a fog light switch? If so, I have several, let me know. Thanks, Collin

I have one from a 90, and one from an 88 I believe. Both would physically fit but might have different plugs. Interested at all?

I'm pretty sure I have one from an 89 or 90. If I do, would you prefer me to chop out just the fuel injector harness or do you want the whole thing?

Does anyone have a write up of how to power the 97+ door harnesses if your MJ came with no power options? Retaining the original MJ dash. Thanks in advance. -Collin

Are you still looking for one? I have the style that bolts under where the console latches for sale. Please pm me if you are. Thanks, Collin

I have an assembly for $40 shipped. If interested, let me know. Thanks, Collin

Mike, Cool to see what you've done to that Jeep. I was the previous owner who did a lot of the work to it. I sold it on eBay to a fella a couple years ago from Omaha when it was still silver. If you have any desire for old pictures of the girl let me know, I have all of them since it was stock. -Collin

Joe, that is a huge help. Thanks so much man!

Has anyone on here adapted a 97+ headlight harness to an MJ? Whenever I have done the 97+ conversions in the past I've just used the MJ harness and settled for just one parking light and modified the other connections. This go 'round we're doing it to one of my friends' XJs and his original connector is corroded anyway so we want to do it the proper way. Can anyone provide a MJ to 97+ color to color wiring cheat sheet for me? Greatly appreciate any help. Thanks, Collin

jpnjim you hit the nail right on the head with what I'm thinking. The only way I'm going to diverge from what you did is take the passenger floor bracing out and weld the XJ braces in exactly the spot they were in the XJs. I already have the charcoal carpet out of a 99 that will be cut down and going in. I'm going to go out with a couple fresh drill bits and try to get some more of these spot welds up, I will keep you guys posted on my progress. Thanks!
