    1993 YJ PCM Issues, why won’t a 1995 PCM work?

    Hello everybody! New member here. I have a 1993 2.5l yj which has been having pcm issues. When cold starting, it’ll run good for approximately 10 minutes before it gets boggy and starts backfiring at 2500 rpm. This limits the speed to under 80 klicks.

I checked the starter (which is basically brand new) and a mysterious wire appeared that I haven’t seen before. My thought is that this wire is my issue for no start. It’s two wires that come...
