what about the "warning lights"? CEL, turn signals, brights, the extra lil stuff
Did you look at the pictures? read the text?

IMHO that gauge cluster rocks..If you dont mind me asking, what do you figure you have in it money wise?
How did you cut the holes for the gauges to fit into?
Some people don't like the accuracy of the factory gauges, especially if they have spent money building an engine. The Jeep PCM will not run the aftermarket gauges.
Maybe I missed something here, but is it true that the Jeep PCM will NOT work with these gauges? I LOVE this setup and would do it in a heartbeat if I could get it to work without 50 hours of work lol.
Hey john d. What size of gauges did you use? Are you using a stock wiring harness? Do you have any measurments for the cluster that you did?
Thanks
Thanks for the info. so are your gauges hooked up to the xj pcm or the 5.3l pcm? If it's the 5.3l pcm than I can just absolete the xj pcm on mine. Would this be correct?
So, I basically finished up doing the 5.3L / 4L60E swap last September. One of my goals was to maintain the OEM Jeep instrument cluster to save the appearance of a stock Jeep.
I ran the Jeep PCM in tandem with the Chevy PCM. I spent some money and time plumbing the 5.3L with Jeep sensors and everything should have work, it didn't. You see, the gauges are fed (I think it starts in '97) by the signals being multiplexed through a buss going from the PCM to the instrument cluster. Even so, my theory was that the proper sensor would feed the Jeep PCM and send the signal to the dash. Unfortunately this wasn't the case. It appears in my case, that the Jeep PCM is going into a sort of auto-shutdown. Countless hours of research (wire diagrams, web searching, interviews with Mopar experts, and seat of the pants troubleshooting) have proven that it is not an auto-shutdown. What happens in my case is, when you go ‘key-run’ all of the Jeep gauges light up and read accurately. When you go ‘key-run/start/run’ the gauges "freeze" wherever they are and will not go up or down until it goes ‘key-off/run’ again. The computer drops communication with the instrument cluster through the start-run cycle. I have spent countless hours over the last six months trying to make this work and I cannot. It is unfortunate because I really wanted my dash to look factory.
