I did this swap in my wife's '88 cherokee with the aw4 and just made a bracket to mount the tps to. That way the original transmission controller still operated the transmission. On a side note I have the Koch adapter from that swap for sale if anyone needs one. After months of work getting all the kinks worked out of this swap making everything work including the air conditioning, her engine lost two rod bearings and killed itself after about 50 miles on the road. (Never trust the previous owner when she says she shut it down as soon as she wrecked the donor mercedes...) In fact I have everything except a good crankshaft for the engine too, now that I think about it. Rebuilding one of these engines is not very cost effective so I went another direction after the failure.

 

WOW that's Garbage! Im sorry to hear that! Especially after all the work..
I have a question on the motor mounts. Selling those? and the AC was custom bracket?

 

My mounts are scrap metal, I cut them off with a plasma cutter, I was that cranky. My mounts used urethane spring bushings and they transmitted too much vibration anyway. I mounted the original jeep a/c compressor where the mercedes alternator was and mounted the jeep alternator where the mercedes a/c compressor was. Both required some fab work, but worked out great for the short time they were in there.

On a side note, I swapped in a 304 out of my cj-5 and the wife loves it (put a 401 in the cj-5)! I didn't gain much in fuel economy like I was planning with the om617, but what a kick in the pants it is to drive now!
(I know this doesn't fit the theme of this forum, sorry)
