4.0 to 4.0 HO swap
Can someone please help. I have a 1990 Cherokee with the Renix motor and I want to put a 1993 HO in it. I am going to change the wiring harness and ECU/PCM along with fuel lines and fuel sending unit that are from an HO. I need to know if there is anything else I need to swap over? I do not need info on swapping an HO in with the Renix manifold and wiring harness. I am doing the whole HO and wiring harness swap so do not even mention any Renix parts.
I have been searching through threads to find all the info I have now but am just covering all my bases.
I want to hear from people have DONE THE FULL SWAP ONLY PLEASE! That is the wiring harness and engine from a HO Cherokee and everything they swapped over like gauges etc.
If youre going to be a smart*** please proceed to another thread
thanks guys

Easy way best way. 93 HO ZJ to 4.6 Stroker. Injector adapters to 2000 intake that's it.

i have a 95 motor in my 90, but not the HO harness.
i don't think you can successfully switch it to HO very easily if not at all.

99 XJ
I figured it was safer and "cleaner" for the forum to revive this thread then to start a new one on the same topic.
I've been eyeballing the net for a detailed full vacuum diagram for my 99 XJ with the 4.0. I want to get a roll of replacement tubing and just do the whole darn thing... 20 years old and if I've got a leak somewhere, well... all the rest of those plastic/rubber lines are the same age.
Anyone know where to track this down?....that is detailed enough to go off of?
