LED Light and push button switch for Flsun QQ Delta

LED holder and mount instructions... Mount will be held with screws already on the QQ.

2 small 3-4 mm holes for the cables to route through.

Wiring diagram shows the correct configuration for the switch to illuminate when LEDS are on.

Start with a small hole 1/8" to 1/4" for the switch and gradually drill larger with a step drill bit upto 3/4", this is pretty tough metal, use a good bit and take your time -
