If you jump the resistors with a piece of wire, you can start the engine.

Thanks, I just wanted to make sure before I hooked it up. I just didnt want to run the risk of hurting a posiably good pcm.

Can you keep us posted on your results ? I'm in a similar spot and can't seem to get straight answers, re ; TBI/CMPFI compatability for the same ECM, 16197427. I jus want to update the one ECM from auto trans to manual , and am thinking I could just swap the manual prom from the TBI ECM for my auto one in CMPFI . They're the same year, 1995 ; I just didn't want to brick a good ECM . Be safe...Bob.
I'm almost positive that there compatible with just a prom change.
As said in your other thread the PCMs are the same, the MEMCALs are not, and in your situation will only complicate things to use the TBI MEMCAL.Originally Posted by romac55
The man who says something is impossible, is usually interrupted by the man doing it.
Jeeps and guns ; keep us updated on this experiment . Thanks for the correction , gentlemen. I'm on the right track now . Hope the Jeep survives . Be safe...Bob.
Just stick the memcal in it and give it a shot. If it smokes... well once you let the smoke out they don't work anymore...

Ive never really had a problem keeping the magic smoke in wires or other devices. Cant think of the last time I let the smoke out of something...
