Yes I have the Premium Peak Amber/White gauge..
Sorry to cut in but, i'm assuming this "yellow" wire is coming from the car which usually represents a constant positive power in automobiles?
I wouldn't go on that theory i'd use what you said first and use a DMM or test light and just make sure you have power when the key is in the off position.
The Cig lighter has a switching power and looses power when they key is turned off so its not a good place to tap in the red wire, but it is an ideal place to get the power for the white wire. Also that little bulb that is in for the Cig lighter that would be a ideal spot for the orange wire aka dimmer. (This is assuming white day amber night, switch the wires for amber day, white night)
If you want to check to make sure your gauge is working right run a test piece of wire from the positive battery lug and to the red wire, if the closing ceremony don't work then, something is wrong. Red is your constant 12V Power not switching power
Also just because you tap into the fuse box don't mean you have a constant 12V.
I'm out installing one as we speak a premium and it only has Red Black Orange and White no yellow
I don't get why mine won't work then.. How did you run it to the fuse box?
