Proper way to wire a ls-30 in a egret 2?

[8bitforlife]

hi I'm trying to figure out how to properly wire a snk ls-30 rotary sticks in an e2. I got 2 of those rotary condenser boards. Do I need to tap the joystick into the player 1 and 2 connection or just run wiring from the 2 connections on pcb to joystick?

I also noticed the joysticks have micro switches are those needed or not needed?

I want to aim for easy cp removal and switch if i change games.

Up, down, left & right microswitches wire into the regular joystick assembly.
Rotary encoder wires plug directly to the pcb.
That's my understanding at present..
