Swap over all of the harness , computers etc , under hood and under the dash , its the easiest way to do it

PM'd back. It is probably one of the easiest engine swaps you can do if you have a complete parts YJ. Even though I went through wiring diagrams, I could not get the body harness to play nice with the new engine harness. I eventually swapped ALL wiring over, and life was good. You will also need to swap the fuel tank, or put an in-line pump. (I use an XJ fuel pump, they are plentiful and have no issues running outside of a tank.)
Good luck. You won't regret ditching the carb.
