RE: 99 3.9L ABS/Check Gages/Brakes light
I had the ABS and brake lights come on for no apparent reason and it turned out to be because of a bad RWAL brake sensor (or speed sensor) on the rear differential. As far as the check gauges light, I don't know of an answer. Are your gauges working correctly? Might be a fuse if the gauges aren't working right. Hope this helps or at least spurs some better advice.
