I want to put the 97+ dash in my truck, but I don’t want to convert to OBD ll. Has anyone done this or know a way to retain the Renix engine management and gauges while swapping the interior? I thought about using a custom gauge cluster in a blank template that fits the newer dash, but I wasn’t sure which gauges work with Renix. ideally I just want to update the interior and allow the ability to run a double din radio with the already existing center dash swap that’s out there. Any ideas would be helpful!

So first, lemme preface this by saying that i have always wanted to build a 97+ converted MJ, in fact i have spent a few years researching the swap and i finally had things lined up to do the swap, including 2001 XJ and an 89 MJ... But life happened and i had to relocated from Florida to Kansas. I had spent several months using a website the searches all of craigslist looking for something interesting to pick up when i came across this. It was 1,000 miles away in New Mexico, made the 26 hour drive in 30. A built Comanche that had been converted to the 99 XJ drivetrain with a 2001 XJ Limited interior. Literally my dream swap. I believe that the 99' is is the best year of the 4.0. So these are the specs the day i bought her: ****Motor**** - Freshly rebuilt 99 4.0 bore over .30 - Bored throttle body - High Volume Melling oil pump - Eddlebrock duel outlet header - High flow intake manifold - Brown Dog motor mounts - IranMan4x4 Brackets ****Drivetrain**** -AX15 5 speed with a new clutch - Np231 transfer case with Chevy HD widechain and gears - 6 pinion planetary ****Suspension**** - 6.5 inch lift - SOA in rear - Spartan lockers - 3.55 gears - 29 spline shafts - Terra Flex high steer - Rubicon Express lower arms - Adjustable Rough Country upper arms - Rubicon Express double sheer track bar - BDS Shocks ****Exterior**** - Loans Metal Products front bumper - Warn 9.5ti winch - 4 LED Pod lights - Bushwacker fender flares ****Interior**** - Interior from a 1999 XJ limited - Heated leather power adjustable seats from a 2001 XJ - Wood grain interior - Correct two window switch installed Some pictures from the day i bought her: Things I have done since having her: - Fox 2.0 shocks up front - Fox 2.0 Steering stabilizer - Rebuilt the winch by replacing the solenoids and cleaning and re-greasing the gears - Reqired the LED lights so they are not a fire hazard and work with the factory fog light switch - Installed a WJ Overland wooden steering wheel with radio controls - Installed IronMan4x4 steering box brace with sector shaft support - IronMan4x4 Steering box bracket / spacer - Rough Country Floor mats - Spooled up some synthetic winch line Here are some pictures of what i have done since having her: And this is what I am currently in the process of doing (I have the parts ready to install): - Installing my OR-Fab bumper and warn M8000-S winch with Rigid LED lights installed on the bumper (from my old 99 XJ) - Creating a new headboard with overhead speakers and the full length XJ limited overhead console - Installing the stock XJ Limited tweeters - Getting the steering wheel radio controls to work with a WJ clock spring Some of my long term plans: - Rear mounted winch - X-Max fender flares - Two tone gloss black and Rhino Line matte black - 4 link suspension - 4.7 stroker - Dana 44 front and rear - Creating a logic board to make my steering wheel radio controls be able to select between front or rear winch, then be able to winch out and in Thank you very much for viewing!! I hope it was worth your time and id love to hear some thoughts and ideas!

So the wiring in my jeep is getting pretty bad, along with the tired renix 4.0 I'm looking to do the dash and high output swap, I found a running and driving 98 Cherokee for $200 I want to take the engine, dash and wiring and swap it into my jeep, the donor has an aw4 but I would like to keep my ax15 I previously swapped into it. Is that a possible option to use a wiring harness that is set up for the aw4 and keep my ax15? Also can I use my existing pedal assembly or will I have to find one from a 97+? Anything else I need to know before I do the swap? Any helpful tips would be greatly appreciated, thanks.

Hey guys sorry if this is already a topic, I can't find it if it is. But I'm doing the 97+ front clip swap on my 89 Comanche and not sure what to do about the header panel wiring harness. Should I use the older one so it plugs in to the plug on the driver side or do I use the newer style harness? If I have to use the newer style harness how would I change the plug to fit the one on my jeep?

Hey gang! My project is moving on to the next phase and I've got the idea that it would be fun to have a 97+ interior with a bench seat and AW4 with a column shifter (I've got my reasons). I've searched and searched, but I can't seem to find anyone who has been down this road before. I'm gonna try it anyway, but it would be awesome if someone knows anything about this swap. PLEASE AND THANKS! It would seem that a 94+ Dakota is the obvious donor:

I got a 2000 XJ as my first car, I bought it from my neighbor who had served in the marines stationed on the Hawaiian islands. Three years later, after spending endless time, money, sweat, and blood on it. Someone rear-ended me, totaled the Jeep and bent the uni-frame out of shape. I had always liked comanches and cherokees, so I decided I would find an MJ to transfer my XJ's heart, soul, and skin on to. I found a 1989 Eliminator in Lake Havasu City, Arizona with 130,000 miles, rust free, and a clean title. It was too good to let go. After an 8 hour drive through a ton of desert and Las vegas at rush hour, in a Jeep held together by prayers, I finally had it home. Little did I know that this MJ had spent time in Hawaii too :thumbsup:

Hey all, I have mainly been just lurking and watching and surfing since I was first looking for my first car. And well, I eventually got a hold of a Fiero from my dad, and while thats a different project, I ended up stumbling onto a 1990, 4.0, 5-Speed, NP231 Sport truck and for 700 I couldnt pass it up. I bought it in October of last year and got to drive it for a month before my LCA bracket on the axle broke off as i was getting off the freeway by my house. I ended up parking the truck while i hunted down a new axle (I wanted to get rid of the CAD system). And while it was sitting, i just kept acquiring more parts to do, and made my to do list longer and longer. Well as of now Its getting: Beijing 2500 Front End Painted Flat white (Rustoleum spray can so scratches won't kill me) with Semi-Gloss Black trim Roof Rack + LED lights (have a 42" Bar already) Custom Front and rear Bumpers with Dual Hidden 12K Winches (Overkill, I know) Custom Rock Sliders And a Claytons Offroad 3-Link upfront and I'm not to sure how much lift itl actually be and a Spring over in the rear 97+ Power Doors/Mirrors So far I have the front end installed and still deciding how to do my front fenders And while I'm doing that my dad is helping out and putting rebuild-able hinges from the 97+, We had to replace the drivers side Door striker area so its got the 97+ door jamb/Striker plate welded in. And the Passenger side will be done to match. I have a lot of the body sanded down ready for paint, I have the new drivers door painted and reassembled and the colors go good together. I don't have any pictures yet, but Ill throw some up tomorrow of my progress... This thread is mainly for me to track my progress and keep track of what parts are from what type of thing, but I figured others may enjoy watching this.

I just bought an 88 Comanche 4.0l 5spd 2WD SWB. I would like to update the front end and the interior. I have found a 1998 Cherokee classic; the body is in good shape but the engine is locked up. Will I need to find one with a good motor in order to swap dash out? I read where the wiring harness is needed in order to swap the dash and have it functional. Is that correct? will the newer harness work with my current 88 4.0? I would like to update interior (dash, seats, center console. My motor is running but needs a good tune up. The 98 Cherokee classic is $500 with blown motor but tranny, transfer case and front and rear axel seem to be good and interior looks good as well. Any information would be great and help a new Comanche owner. Thanks
