[QUOTE="Lasherž, post: 8711456, member: 679555"] Volt meter displays use virtually no amps at all, like 25mA max so you could use 26AWG if you wanted unless it has a very bright LED display, even then 20 will be fine. It's pretty simple, you just hook it up to the positive side to + and the negative side to -. The more important part is determining where you want the monitor to go. There's voltage drop throughout a system, so if you want to monitor the power going to your amp I'd wire it up close to the amp inputs, or if you're monitoring your rear battery voltage I'd go as close to those terminals as possible. The only safety related part of it is to make sure there's no frayed ends on the wires that'll contact each other. What meter is it? Some of them turn off with the car so as not to drain the battery.
