ok bought a switch for my anti lag and it has a light on it.

it has 3 pins


+
A
Earth

ok well with anti lag you need to put one wire in from ecu pin and needs to be switched to earth

on of these pins is for light on switch which one?

 

the light will become illuminated when the switch is in the on position, but since your switching the neg not the poss im not sure you could wire it to light the lamp unless you also used a small relay.

 

i had the problem, you can only realy use those small switched with the lights in when switching the postivie feed,

let me have a think and look at a diagram
