stock computer under dash necessary?

My 4.2 CJ has been nuttered for years, and recently i stripped the interior for line-x. Currently the computer under the dash is sitting on floorboard. Is this thing necessary or can i unplug it and remove it?

Unplugging it should be fine. I'd unplug, try to start it and check that reverse lights work.

If its nuttered , isn't it bypassed anyway? At least that's how I understand the mod.

Well there's 2 computers, one is on the driverside fenderwell. Which gets removed with the nutter bypass. But i don't know about this one. I was thinking maybe it still had power wires going in and out of it that still powered other things like the dash?

You've got that backwards. The nutter takes the computer under the dash out of the equation. The ICM on the drivers fender is still required whether it's nuttered or not (unless you did a stealth HEI and/or team rush upgrade as well)

'84 CJ-7: Yota axles (spartan locked front, e-locked rear) 4" BDS, 1" Daystar & 3/8" shackle lifts, 35" X-Terrains on steelies, YJ Tub & family roll bar, heater blower upgrade, 4.2L w/MC2100 & Team Rush, Warn 8274. Rebuilt 4.2/4.0 hybrid, AX15 and twin sticks/clocking ring waiting to go in.

The advertised position for a topless, dirty jeep girl has been filled......by my wife. Thanks to all that applied.
<------------and yes, that is her.
:-D

Close, but not quite. The ICM on the dr. Fender controls spark and is needed, unless. A stealth HEI, MSD box, or HEI Distributor is used. I wouldn't call it any kind of computer.
I believe what the OP is asking is the box above the glove box, behind the dash. This is the one the Nutter bypass does away with. Neither of the 2 have anything to do with anything on the dash.

Anyone have one of those ECM brackets from their heater ducting they aren't needing? Would like to put one under my dash for the future 5.0L swap... I've read those are the same size as the Ford EEC-IV modules.

Probably just set it with the rest of my CJ stuff in the basement.. I have almost enough spare front and back seats from multiple CJ's to create a theatre down there!
