Ok, so I installed a simple intercooler sprayer in my car. I wanted a very simple sleeper setup so i bought a cheap and simple rocker switch from walmart. Its the kind with three blades and an LED that is SUPPOSED to turn on when I turn the switch on. The problem is........ ITS NOT! I've tried everything to try to make it work but I can't. I have it wired like this: The positive lead to the pump is connected directly to the positive battery terminal. The negative wire runs from the pump into the cabin, where I have it connected to the switch. It then runs from the switch to a ground point in the cabin. The switch itself has three blades. If I connect the incoming wire to the 2 blade and the outgoing ground to the 1 blade, the light comes on when I flip the switch but the sprayer doesnt turn on. When I connect the incoming to 2 and the ground to 3, the spray comes on but it wont light. If I ground 1 AND 3, it will spray but not light. I have also tried tapping the hot wire from the boost gauge and hooking it to the switch and nothing happened. Can ANYONE help me with this? Thanks.
