4.3 l swap for 2.5 l in tj

I am currently in the middle of swapping in a 4.3 l in my 97 wrangler (in place of 2.5). I have all of the mechanical stuff done. I am currently working on the wiring. I would assume I would need to keep the fuel pump and speedometer from the jeep wiring and use the jeep computer to run the dash. I would assume I would need to keep the same jeep wiring as someone swapping g a GM V8. For those who have done that swap, do you have advice or wiring diagrams on what jeep wiring to keep. I have had the GM harness and computer redone to run stand alone.

You won't use the jeep computer. You will just have to research what adapters you will need to make the gauges work with the 4.3 ECU.

The GM 4.3 uses a lot of the same parameters as the gm v8s.
