Thanks for the info, that's indeed what I did assume. Yes the vehicle does start and run, given the battery does not receive a charge due to the connector not connected to the alternator.

Hi all, I'm fixing my buddy's truck while he's out of town as explained in another post I made on this forum. He swapped in a 2001 XJ Engine and Trans and into his '90 Comanche. The wiring is the original comanches. I took a look and seems like he still has his XJ alternator. The comanche alternator wiring is this l shaped plug here: His alternator requires a plug that will fit his alternator as seen here: I am not certain at all that he has a voltage regulator already installed, so just to be on the safe side, has anyone made this conversion before or has a suggestion for a conversion kit for this? Thanks all in advance.

Hey Eagle, Just curious if you managed to take a few photos of the clutch pedal from your 2000 cherokee. Hoping I'm not off to buy a new clutch pedal, and possibly it's just been installed wrong. Thanks in advance!

You have your 2000 clutch pedal mated to your comanche? Hopefully now after the photos I submitted you can see why the fuse-box does not fit.

Oof, you asked about the two things that aren't hooked up. No A/C has been hooked up,, so the compressor is sealed for now, and my roomate would prefer (I don't know why) that it isn't... and the radio is with me, but I haven't tried installing it yet until I get the whole interior sorted out.

The motor is running off the original MJ ECU Here is all used in the fusebox:

Perfect! I was just about to ask of photos with it depressed. Thank you SO much. I was incredibly worried we'd have to cut out a new firewall to have it mounted.

Thank you incredibly much for those photos. So our hunch was right, we were doing everything we right, it just seems like the clutch pedal needs to be replaced or somehow fabricated to not directly depress over the fuse box.

We tried this. Still no room. There is currently a metal bracket fabricated to keep the rain and water out that covers the firewall that the last guy who helped my friend made. Here are photos to show what's going on currently and how the clutch almost touches the firewall. It basically has about half an inch of space with the clutch fully depressed. I have a feeling that the clutch pedal might need to be replaced with a comanche as the bend causes it to basically depress directly over the fuse box.

Gotcha, okay, thanks for the clarification. Perhaps then it's the clutch pedal (being it is from the cherokee, that is different than the comanche. Or perhaps it's the dash that is from the cherokee that is causing it to be difficult to mount the fuse box. Thanks again!

Sure thing! Here are some images that I took a month ago so they are not currently reflecting the engine bay, however here is a video of it running last night, it's short, sorry but I'll definitely be making a longer and better coverage video here this evening when I drive it around. Link to video of the comanche running:

Awesome, thanks for that heads up, I'll be assembling it a bit more this evening and will glady take your suggestion.

Sure thing - I've put together the interior a bit since this image (steering wheel, shifter, 4wd lever etc.) but since I'm not in front of it right now at the moment, here's what I've got.

I thought this originally, but it starts thanks to the mechanics who realized it was not completely all spliced together and mostly all intact, most of the lights work, I’ll have to build a switch for the radiator aftermarket fans, it’s just the fuse box and block that are currently zip tied under the dash. That’s the only remaining issue really. I’ll definitely reiterate that it wasn’t my idea to do all of this for sure, this was just the result of trying to sort his friend’s wiring out to make it work in time. Hopefully It won’t require a complete rip out - I’ll send over some photos tomorrow of the work done so far... but you guys know better than I...

Hey Dzimm, the engine, transmission, and all of the interior, minus the headliner and carpeting is a swap from a 2001 Cherokee. The electrical (mostly) was a combo swap between the Cherokee and the Comanche. Seems like about 80% of the electrical is from the Comanche, The guy who helped him out seemed to stop at the interior fuse box and block. The issue I'm facing now is just properly mating the fuse box (from the comanche) to the fuse block (from the cherokee it seems?) There is just not enough room for the clutch to depress and I can see that it because the dashboard and panels are all from the cherokee.
