Kaimana mini and Kaimana adapter for RGB LED JLF joystick


How do you guys connect an rgb led for the joystick on the kaimana mini without the kaimana adapter. It seem’s to no longer be available on paradise arcade shop. I was wondering if there is a workaround with 3 resistors ? The only information on the site is : Resistor suggested: 1/8W VAL 120E
What would be the exact ohms value ?

I’m using a brook universal fight board and I ordered a kaimana mini kit for the button and I would also like to add the joystick.

You actually need it because it has a chip on the adapter I believe. I think I have an extra. I can mail to you
