I was just about to post asking about the UltraGauge Automotive Information Center and OBDII Scan Tool I'm thinking about ordering.

Seems to read/show just about everything you could want and displays up to 7 gauges at once. Also very nice price in comparison to similar OBDII stuff. Has anyone tried one of these?

As a secondary question, where exactly is the OBDII port on a 98-03 GP?
