feerocknok Posted July 18, 2007 Share Posted July 18, 2007 I'll beat everyone to it and ask: Did you have to modify the '86 firewall at all for the 4.0? Link to comment Share on other sites More sharing options...
Kenosha Warrior Posted July 18, 2007 Share Posted July 18, 2007 What did you do with the 2.5L motor and accessories. There's a guy on here that needs the 2.5L alternator specifically for a motor with air conditioning. Link to comment Share on other sites More sharing options...
M2 CARBINE Posted July 18, 2007 Author Share Posted July 18, 2007 No i did have to touch the firewall all i had to do was move the motor mounts i didn't even have to drill any holes to mount it is all there.I gave all the 2.5 stuff to my uncle Link to comment Share on other sites More sharing options...
carnuck Posted July 18, 2007 Share Posted July 18, 2007 You didn't use the crank sensor from the 4 cyl? Link to comment Share on other sites More sharing options...
Oizarod115 Posted July 18, 2007 Share Posted July 18, 2007 You didn't use the crank sensor from the 4 cyl? double check on your sensors, after our motor swap (4.0-4.0) sometimes it doesnt fire up just cranks and you wiggle the wires that come from the CPS at their connector and vroom vroom...

M2 CARBINE Posted July 18, 2007 Author Share Posted July 18, 2007 I used nothing from the 2.5 engine.I pulled everything out and put all 90 xj parts back in. I slide the motor,trans,transfer case as a single unit and then put all the wring harness in. Link to comment Share on other sites More sharing options...
Scott86mj Posted July 19, 2007 Share Posted July 19, 2007 I used nothing from the 2.5 engine.I pulled everything out and put all 90 xj parts back in. I slide the motor,trans,transfer case as a single unit and then put all the wring harness in. That is how I did mine. When I Connected the engine harness to the 86 2.5 bulkhead I couldnt get it to work. The pinout was different. I just removed the fuse panel and the interior harness from the 94 xj installed it in the mj and it fire up. Link to comment Share on other sites More sharing options...
M2 CARBINE Posted July 19, 2007 Author Share Posted July 19, 2007 I left the interior fuse panel from the 2.5 in. Do i need to replace it with the one from the 90 xj? The only thing i replaced was the gauges what else do i need use? :bowdown: Link to comment Share on other sites More sharing options...
M2 CARBINE Posted August 20, 2007 Author Share Posted August 20, 2007 I'm thinking of selling the mj above i just don't have the time to fix her up anymore. I went from working 4 days a week to now 6 days (at the paying job) ;) so what do you guys think she's worth I've added the following 4 Bilstien shocks 2 Jks swaybar dics 2 Rusty's 4.5 coils 2 1.5in spacers 2 bucket seats full Center console Spring over axle conversion thanks for the help Link to comment Share on other sites More sharing options...
JeepcoMJ Posted August 20, 2007 Share Posted August 20, 2007 no clue what she's worth and sadly, I have too many. yes, you need to put the fuse box from the xj in it...the stuff from the 2.5 is wrong. the wrong part is the connector at the bulkhead that you connected the 4.0 harness too, all of the "pins" (metal connectors) are in a completely different order. so you swap that in, and she'll fire. oh you will need to do some wire splicing and in this scenario, clamping the wires is NOT a good idea. neither is electrical tape..when it comes to this you should consider soldering it all together. I think you should keep her and work on her every other sunday til she runs...it's only about 4 hours of work left. last thing, on the fuse box, you will be cutting out wires. but you won't be cutting one single wire that's between the fuse box and that bulkhead (firewall) connector. don't. that is the problem area right there, and the point of the fusebox swap is to replace this.

M2 CARBINE Posted August 20, 2007 Author Share Posted August 20, 2007 There are at least 60 wires going from the fuse box to who knows where i would be lost in no time if i did that. Wiring is not my strong point at all! P.S I forgot to add i put YJ brakes lines in the front and dakota line in the rear last week Link to comment Share on other sites More sharing options...

Wiring is not my strong point at all! P.S I forgot to add i put YJ brakes lines in the front and dakota line in the rear last week you'd be splicing about half that. because the other half goes directly to the firewall connector...so that would be the solution to the problem other solution, rip out your dash and put the entire interior harness from the cherokee in it. then the only wires you have to splice are for your rear lights, and your rear speakers and B-column lights. on a scale of 1-10, I'd give the wiring swap a difficulty level of about 3 when it comes down to it. is it costing you money to have around? will it be cool to have functioning when it's done? if the former is no, I suggest keeping it since you're making bank anyways...and fixing it slowly Link to comment Share on other sites More sharing options...

M2 CARBINE Posted October 29, 2007 Author Share Posted October 29, 2007 I just got done wiring in my new fuse box and found this under the dash notice it says Aug 26 1985 Link to comment Share on other sites More sharing options...
feerocknok Posted October 30, 2007 Share Posted October 30, 2007 Yeah, it's an '86 though. Like the '08s are already coming out now and it's 'Oct '07. Nice to see the full gauge cluster! Definitely more important than it would initially seem, but I know I watch mine constantly. Link to comment Share on other sites More sharing options...
M2 CARBINE Posted November 12, 2007 Author Share Posted November 12, 2007 well i can't figure out why I'm not getting so much as a click or fuel pump sound when i turn the key i replaced every wire in her (Went pretty smooth) can anyone give me some thoughts? thnaks Link to comment Share on other sites More sharing options...
Oizarod115 Posted November 12, 2007 Share Posted November 12, 2007 did you swap over the little ballast resistor thats on the fuel pump wire? on the 4.0 it would've been on the drivers side fender area mounted near the vacuum switch for the EGR that thing can crack/break causing the fuel pump to cut out and/or not work somtiems Link to comment Share on other sites More sharing options...
