ok so i bort a few gauges and i ran into a little hitch, i am unable to find two wires nessesary to make the dam things work, as its an electrial gauge i need the ignition switch wire(i think its yellow one??) and also the the dimmer power wire or dash circut wires in order for my back light in the gauge to turn on. If any one knows the location and colours of these wires it would be a great help.
