Help with echo board

[Rascal058]

I bought a LT-2N ranger -2019 board. It came with no instructions.. I wired it in a cobra 29 classic. It works, but on the control switch there is a capacitor , one side is soldered to the switch, the other side nothing. What is this capacitor for and what goes to it? Any help will be appreciated

Are you referring to the ranger eb-2015 or the pro trucker lt-2n which I think you have because it comes like that. The capacitor isn't always necessary but it goes to chassis ground if needed.

Used to see the other leg of that capacitor soldered to the metal body of the control.
