90 yj... take out computer?

ok gonna make a long story short...i have a 90 yj with a 4.2l webber carb with a crt performance dizzy.. now back to the story...im finally getting my frame fixed by a very good friend of mine and he told me he cut the wiring harness to the computer.. do i need the harness and computer for anything..? does the instrument cluster go threw it? i wish he didnt cut it but he said it wasnt hooked up to anything ...so what do u all think

Computer
OH YEAH you mean that thing mine USED to have years ago before I made it much more dependable and efficient.
With a webber and CRT the only thing you computer has to do is look at the O2 level while it plays with itself.
Remove it and you will see a big performance gain..that pound and a half of anchor is really slowing you down

you might want to leave it in case you sell it and want to put a stock carb back on. I wish i did. Just unplug it.

You want them? I got the carter, dizzy and computer in a box in the garage attic.

I still have everything but I trimmed the wiring harness down to the bare minimum. I'm about to do a junkyard fuel injection swap but thank you anyway.

Too late if it's cut now, may as well toss it.

I have a spare too, because I did a FI conversion and saved the parts.. figured someone might need it to pass inspection.

It's not doing anything anyhow with the mods that are already on the Jeep. Physically removing it isn't going to change anything.
