renix to H.O swap

i am pulling a motor out of a 94 jeep with an ax-15. was pulling the harness without cutting anything so that i could use it if i swapped the motor into my jeep. my question is how much of my harness will work with the high output motor? am i wasting my time keeping the original harness together?

the motor only has 380 miles on it. not 380,000 just 380 miles. it sat its whole life. i figured i couldnt pass it up. not sure if this was mod tech or oem tech but move it if i posted in the wrong area please!

Thanks,
Mitch

Don't use the HO fuel system, more trouble than it's worth. Just use that engine with the Renix manifolds.
