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!
