?Wiring battery level indicator into Flipsky 4.2 with antispark switch

Hi. I am trying to wire in a battery level indicator. I have a flipsky 4.2 with antispark switch. The switch has 3 wires (red, white, black.) There is no break in the leads from the batteries, to the Vesc. The switch plugs directly into the esc board. I want to wire a battery level indicator, but not have it on all the time, while the batteries are plugged in. Other switches are easy, in that it simply goes after the switch. However, I was wondering how I can do this in the switch wires. My battery level indicator is the one that most of us have. With one red, and one black lead. Iā€™m thinking I might wire the indicator to the black and white leads. Any suggestions are greatly appreciated.Thanks

positive and negative of the indicator sits between your vesc and your switch in the circluit.
