MrDiesel,

DCreed is correct, it is simply an on off switch. When the box is correctly wired the red light is always on when the key is on and the switch is on. The yellow light shows the boost harness is connected correctly. The green light comes shows fuel is added, the brighter it is the more fuel being added.

If you have a remote then the switch is unnecessary.

GREEN MEANS GO!!!!

Godspeed,
