88 Renix 4.0 Into 95 2.5 YJ?

Having trouble with wiring. All I am finding is newer engines going into older jeeps. Any help with this would be greatly appreciated.

Why would you do this? To swap in a current 4.0l you add 2 injector wires and extend the temp sensor. Swap in an ecu from a 4.0L and you are off tothe races. The earlier renix engines require a bit of adjusting for the sensors. If you are looking for info then use google search like this:

You can't find any info because people generally do not go backwards from a FI 95 to a Renix system. Peolpe consider the Renix system to be problematic in a stock vehicle much less a swap. I would highly recommend ditching the Renix system and upgrading to a modern FI system now.

I had a remix cherokee and never had a problem that was any worse then a normal vehicle. If you dont know how to use a multimeter, dont do it. I have thought about this swap too, if I had a donor.

You can use the block and just get the fuel injection stuff if the block is low miles. I am just leary of the renix if you are not very well versed with a meter and you dont understand the potential issues.
