I got a new Volt gauge, it has 4 wires, Red, Black, White, and Orange---any ideas where I should connect these, I mean back and red are obvious, but the white and the orange got me beat, any ideas?
 
For the light bulb? I think they are seperate.

What is the brand of gauge? but white is most likely going to be wired into the dash lighting, and orange is probably going to be a the signal wire
 
Hoow one to a 12v source for the headlights. Hook the other to ground. If it is a standard light bulb, it does not matter which way the electricity flows. It will light all the same.
 
 
the guages are "swoosh" with L.E.D lights
 
Just play with it. If you hook it up wrong the LED will not light up and it won't hurt the LED.
Try it on the battery of the car to figure out which wire is positve.
 
 
Are you sure its a volt meter and not an AF meter?
 
 
no its a voltmeter from swoosh! Got them off Ebay! Will try to play with them when it gets warm and then we will see!
 
Well here are some specs, maybe someone has a better idea now.
