I'm helping a buddy work on his Mario Kart arcade GP. It's missing the center button on the steering wheel.

Can anybody that owns this game either take pics or let me know which color wires go where on the microswitch / lamp assembly.

Thanks!

I put the red/black power (5v) wires on the lamp and the other two on the switch but not working.

I figured out the wiring on the Item button in the center of the steering wheel. He can now throw items but the light that's supposed to come on when you're ready doesn't light.
