I have an aftermarket radio and my dash lights won't come on, I can't see how fast I'm going at night. When I crank the engine they light up but as soon as it starts they shut off, I probably mixed up a wire but not sure which one it could be. Any help is greatly appreciated!

 

Disconnect any wires you tied to the dimmer/illumination orange wires on the head unit, and/or tape off any unused wires.
