Okay, so I'm a dumbass and have had this thing sitting on a shelf for so long that now that the time has come to install it - the wiring instructions are missing!
Anyone have one of these gauges who can help me figure out the color code?
Wires on gauge are red, black, orange and purple. Wires on sensor unit are red/black. Beers at the NG for the person who comes up with the answer.
