Uh oh, no wiring diagram for the MSD? Nope, got that...just having a hard time figuring out where to hook the MSd "trigger" wire and also having trouble integrating the old 2.5 harness with the new 4.0... Every available connecter is connected...that was the easy part. I'm just having a tough go of it...I've been at it solid since 5 AM this morning, and I know...I KNOW its something stupid and simple, but I am either to dumb to find it, or too tired to catch it...lol (not to mention how crappy the original wiring was in the XJ, there is stuff in that harness I have NO idea what its for) I think I am going to call it tonight. Some good news however, is that with the power hooked up, I can get the starter to crank (shorting it out on solenoid) and it turned over ok. No major problems for seen, and it seems as though its a pretty tight motor. Will find out for sure when it finally fires. If there is anyone available who could help me with the wiring tomorrow, I'd be MOST appreciative. Once the wiring is completed, I just have to drop the tranny, fill the converter, and replace the tranny. Top off all fluids, and I should at least be able to move it under its own power. The rear driveshaft will likely be too long now, but the front one should be perfect, so I can at least drive it in 4wd (front wheel only). OF course, I still have to fab up a cover plate, install a shifter, install t-case linkages... so much to do still (can you tell I am tired)

I'd be glad to help, but no can do tomorrow. In fact, I need to be up in 5 hours to go to work. If you want to, I've got a compression tester, so we can check just how "tight" the motor is once it's up and running.

Any luck with that thing James? Nope, no luck as of yet, but I did find out something very interesting tonight.... Turns out that when the motor was pulled from the XJ, and I left to go get tie downs, and such, someone (ok, everyone helping me) decided to pull the rotor out of the distributor, thinking that I would get the motor in and wired pretty soon, and it would never start without the rotor... Guess they felt sorry for me after seeing my wiring mess, so tonight the MSD rotor was returned to me by Rstep....thanks guys...the game is on now and I don't always play fair...lol muuahhhahahaha Anyway, progress report....well, simply put, if I apply direct power to the starter, she cranks right over...this is important as it tells me nothing in the motor is broken, bent or otherwise damaged. Started splicing wires and temping things in...I can get the ASD and starter relays to click over, but the starter itself will not turn over. After pouring through diagram after diagram, i'm getting all crossed up in my head. I think the best thing to do from this point is open up the old and new harness completley, and trace wires.... my old motto was "plug and play" my new motto is "one fu*&(*ng wire at a time" I never have gotten into the engine bay wiring much, so this is all new to me. I know the basics...spark, fuel, air....voila...fire...Fuel is covered....need spark... Anyway, anyone who is familiar with the basics working of a motor, and the wiring (just general would help), I could use your help...food and beverages provided at my house for anyone interested. My goal and timeline to have this running is thanksgiving.

Wiring? Sounds like fun! Should I bring the marshmallows? ;D Seriously though, what's your schedule like? Wednesday just got screwed thanks to work, and I'm gettin' sliders by Greg on Thurs/Fri. I was going to trundle down to the work-o-thon Saturday, but sounds like you need an assistant, and I'm slightly familiar with wiring. Even those pesky ignition systems that still require a rotor.

Anytime after 5 PM I am home...thanks for the help slick... I actually got the ignition halfway there last night. I can now crank over the starter from the key, so thats a big start...now I just need to find out where I hook the MSD trigger wire on the 4.0, and it should be good to go.
I've got fuel, and with one wire I should have spark. Computer has power and is all set to go.

Good thing I have Slick, me and electricity.....bad combo ...nuff said. Anyways, rotor should help you a bit once the wires are cooperating. ;D

Time to reach back into ye ol' memory... There was a MSD wire that had like 3 splices to it that went to the original ignition box. Trigger?

Time to reach back into ye ol' memory... There was a MSD wire that had like 3 splices to it that went to the original ignition box. Trigger? Yep...I found it....(meaning I didn't even have the ignition box in the system as it was still on the floor)... Anyway, hooked it up, messed around with the previous owners hack wiring including the adjustable map sensor and the kill switch and guess what I got... fuel + spark + air = FIREIt took her a few cranks, but she turned over and CAUGHT....the only problem I have is that the only way it stays running is if I hold the key in the "Start" position. If I let go and it goes to the "run" position, the motor dies... What a relief to at least hear fire though... Not knowing what condition the motor was in from the wreck, it was awesome to hear her fire right up, and she sounds PLENTY healthy as it vibrated the entire house.... Now I just need to find out the problem with the "run" feed and at least the motor is good to go. THen I'll start looking into the gauges and what not as well as the rest of the mechanical stuff such as the tranny mount, drivelines, and what not... I still have to drop the tranny and fill her with fluid. I've only run the engine for 20 seconds at most each time, so it should be fine...

Oh, and well I'm about it, you just need to make sure the ignition is hooked to the "run" position as well as "start."

Oh, and well I'm about it, you just need to make sure the ignition is hooked to the "run" position as well as "start." Yea, I figured that much out....and I found the wire from the original YJ harness labeled Ignition Feed (Run Only) but I cannot determine where to hook it to the XJ harness.

And while I didn't do the deed, it was thought of while I was trying to figure out how to dismantle something else in such a way that it would be easily put back together.......

Very nice good to hear that you have gotten her started! Well, got her started again, and this time I was able to let go of the KEY...after STARING at the diagrams for about a half an hour, I noticed a BL/WT wire running through the ignition circuit...Sure enough ,I hooked it up and she is ready to roll. I also cut down my old shroud to make a new one and mounted the radiator permanent. Tomorrow night, I'll start cleaning up the wiring working back towards the ECU. I still have to get my gauges working, but that should be a bit easier than the crap I've dealt with so far... ;D

Sounds good! At least she can keep her heart running without dying, all in all that was a fairly quick turn around for the engine swap to a breathing engine! ;D

At least she can keep her heart running without dying, all in all that was a fairly quick turn around for the engine swap to a breathing engine! ;D Thanks...still a LOT to do, but now its just tidying things up getting the drivetrain bolted all the way in (tranny mount, t-case and drivelines). Of course, I still have to drop the tranny to fill the tourqe-converter, but thats the last MAJOR thing to deal with. After that, I just have to decipher the gauge wiring. Hey, does anyone in town know where I can pick up a kick ass fuse block? Perhaps a stereo shop? I'll look while I am out to lunch today. The XJ harness did not use a PDC (Power Distribution Center), but rather had all the power going to the battery. If you were there when I pulled it, thats what the taped up copper terminal was...all of the power. My plan is to pick up a fuse block, that can accept 10-15 power outputs with one 4 or 6 AWG input. I'll get some pics of everything tonight..... Its coming along nicely..Of course, anyone who wants to see and HEAR it in person...my garage door is always open.

So, I went by Audio Express and picked up a power distribution fused block...cost me some change, but I think it will work quite well...1/0 AWG Input, 4/0 AWG Output (unfused) and four 4/0 AWG or smaller outputs (fused)
Tonight, I'll get the passenger fender buttoned up and start cleaning my wiring mess up, working it all back towards the ECM. The biggest issue I face is the power distirbution, thus the reason I got the aforementioned block to a help me with that matter.

no offense why even bother with the 6 (maybe you got a good deal on it) but i would go 8 just my own hopes to do someday. just wondering why you choose the 6 not trying to start a debate.

second time on this site and didn't know there were more pages are it sounds like your putting a whole drivetrain from a cherokee in with auto? just trying to keep up.
