Thanks, I'm asking about the switch itself five connections on back and no instructions. By the way I did your first stage of the air intake it looks great and i'ts much easier to change of clean filter.
If you have just an ON-OFF switch with LEDs, then I think I have the switch wiring on the How To. If not, I think this is it. The first is the 4-connector.
Then the 5 connector.
Or better yet, this one but the color code is for the RPM limiter override I replaced my momentary switch with one that stays on. You will use the gray/black and the green/black and nothing else unless you want to tap-in to the dash LED 12V power and the ground. DO NOT use any power or ground from the thermoswitch to light the switch or provide a ground for the switch's lighting:
