Gauge question

[Lost1wing]

I read it still have no idea what it does

This is the hook up kit. Ubd2 and separate power input. WT57005.
It is programmable for what ever you connect it to. Good find jac04!

From Wagner
"It reads values within the ECU such as boost pressure, speed, rpm, ethanol content if any, trans temps, coolant temps, etc. It is a display for most sensors."

I cant trace the wires right now because the jeep is in the shop. When they serviced it they didn't tighten down the rear diff bolts, I noticed the oil spots. Bolts were only hand tight. When i pull the dip stick the magnet was covered in metal shavings and a needle bearing and no oil on the stick
