After doing some searching I see the popular thing is to put the HO head on the Renix block with Renix intake & exhaust manifolds...

Does anyone know if there are any write-ups on swapping the HO motor and CPU into a Renix? I have a wrecked 94 4.0L with a 5spd I am looking to swap into an 88 Renix AW4 as a whole, rather than just swap trans.

Other than fuel lines & cooling system, what all would have to be done with the wiring harness to change complete engines and CPU's? I have someone who would want the Renix drivetrain which is one of the reasons I want to swap the whole setup over.

I know this subject has been discussed several times, but I haven't really seen much on doing the full swap. Would it be better to try and swap harnesses or look into buying an aftermarket harness?

 

Look up "cruiser54's mostly renix tips". He has a write up on it.
