Hello. My new is Kerie. I'm on here to ask a question for my ol Man. He is wanting to know if you can use the computer ecm from a 1996 Jeep Grand Cherokee on a 1994 Jeep Grand Cherokee with a V8? Any help would be great as it is our only vehicle and it will not hold a charge.

 

I'm gonna say no. pre 1996 vehicles are obdI...post 96 are obdII...completely different systems.

 

Any idea what else could be keeping the battery fromfrom holding a charge with the regulator put on?

 

Draw on the system somewhere, or, just a bad battery.
