Engine: 4.0 HO
Default 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

Is there a problem with the engine you have now or you just want more power?

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.

You can, but it's all for naught.

Do what you did, and I've done many times.
