Hi, this is gonna sound a really silly question but here goes.
I have a volt gauge with red, black and yellow wires coming from it. I was going to connect it up to the cig lighter.
1. red/red, black/black, yellow/yellow
2.red/black, black/red, yellow/yellow
a silly question i know but just want to be 100% before i do it, as i dont really know that much about electrics.
Hope someone can help thanks
