Default 1992 Cherokee 5 speed swap

Yesterday I went and picked up a complete 99 5 speed cherokee for $300 to swap into my 92. After looking at my 92 I noticed that I have no punch holes on my firewall. And right where my slave cylinder would go I have my computer there. My 92 is in a lot better condition than the 99 and the 99 is also full of mold, thats why I was hoping to swap. Is there any way to make this work or should I just run the 5 speed? I also noticed that the pedal assemblies are different so that might be a problem as well. Any help is much appreciated. Thanks.

Okay so I have done this swap, and am working on writing up the thread in the next week or so after I move. I do know mine had the hole where the clutch master cylinder went, right behind the brake booster on the fender side. Just needed to drill the mounting holes and the new brake/clutch pedal assembly will be on the other side of the two holes. I didn't need a PCM, but I also have a check engine light and the codes are all wondering WTF is going on with the transmission.

Some things to consider:
  • PCM (computer)
  • pedal assembly
  • reverse lights
  • brake light sensor
  • transmission tunnel cover
  • center console boot
  • Neutral Safety Switch

I can only attest for what I have done. I swapped the engine and manual transmission from a 1996 into a 1999 that had a broken engine and automatic transmission. I needed the those parts plus the pedal assembly and transmission tunnel cover. I would be interested in trading a few parts if I understand the situation, the the 1999 was a manual transmission for you?

I would need the center console bezel, PCM, and the manual transmission wiring, I would gladly trade the PCM and the AX15 wiring from the 1996, unfortunately the bezel I had was broken when I bought it but you can fond them on eBay if I remember right.

PM if I don't respond on this thread. I look forward to seeing another manual swap on here! I really isn;t that difficult once you get passed the pedal assembly!

Thought that maybe having an external slave would make a difference since that started in '94 but I should still have punch holes somewhere right?

Take some pictures of the firewall, mine was a plug that was painted over and semi difficult to see.

Ill get some pictures in about 2 or 3 hours. Going to run up to a local wrecking yard and check out an 89 to where the master cylinder is bolted it.

From a jeep at the wrecking yard, I totally forgot to take a picture of mine yesterday but this one is identical to mine. I decided to just drill a hole above the computer. I dropped the manual out yesterday going to drop the automatic and then work on fabbing the pedal assembly and master cylinder after work. Ill take some pictures for anybody else looking to swap

Okay so that picture helps, There should be three holes, I would just measure from the lip at the top of the firewall to match the 1999's. The picture looks similar to the 1996 I had and mine were similar distances from the top of the firewall.
