I'm not bad with most things car related but I suck with wiring so I was wondering if anyone could help me?? I've bought a boost gauge. I know how to get the boost gauge working, but I have no idea about the wiring for the LED backlighting?? It has 4 wires pictured here:
I know black is the earth wire and I assume purple is positive, but clueless as to what the orange & yellow ones are or where to connect any of them? I'm fitting in the DIN slot in the center console.
Any help is much appriciated.
And as a bonus here are the instructions...
