I need help on wiring a voltmeter on a quad 18650 paraseries box

Hello, my name is Eddie. Im a 7 yr veteran vaper, and need some advice on a box I built. I hope I'm posting this in the right spot. I've built a quad 18650 paraseries box w/ a mosfet. It works awesome. Only thing is, I want to hook up a voltmeter and I'm not sure where to wire it to. I would like it to only read when the fire button is pushed. With or without load. I've built tons of boxes, but have never used voltmeters on any of them. I would really appreciate some input. Thanks all

I would assume that you would want to connect to one end of your vm to your 510 and the other to the opposite to your sleigh so when you fire it draws off the pull for the atty. I personally would wire it in with a switch dedicated for it
