I mounted this meter in a bus using the mounting cup. It looks nice. I originally mounted this under the defroster duct and I noticed that it would stop responding if it got warm. It appears the meter was warming from being mounted to the duct. The heat would conduct through the mounting to the meter. I noticed this because when I would go to start the bus after driving a while, the meter would not reset. I have relocated the meter and the problem has gone away.

Matches my Dodge '05 2500 well. DEFINITELY requires a good ground. Had some trouble with my gauges resetting. After the lights were dimmed ALL my gauges would reset and the dash lights would go out. Redid my grounds and all is good. Need to make sure you buy either a cooler line built to accept it, get a coupler and fill it with the thermal compound or rig up a "T" someplace in the line.All in all, the gauge works well, no problems!

Description states factory match for my 2004 Dodge Ram, but it is not a factory match. It is close and looks good. Also, the plastic mount needs shaved down if you plan on installing into a-pillar pod.

Installed 2 weeks ago and it's working great! Pointer is steady. Looks well made. Hooked lighting wire to dimming wire. Works well.
