I just got one of those analog led volt meters by smd and wanted to put it in. Just wanted to make sure first that I'm correct in thinking I can just run long runs of regular 18 Guage from the wire harness from the head unit to the meter itself right? The instructions say red is + black is ground and yellow is remote turn on so I'd just wire red to + on the head unit harness black to ground on there and then just tap into the turn on for the Amp correct? Just wanna make sure im doing this right before doing it all the wrong way and it not working lol thanks guys.
