K so I just wired up my kc daylighters (130w spots). It was a full kit to include relay, fuses and switch. I wired it up per the directions: supply from switch to 12v source (+ side battery); load from switch to relay to ground (- side battery); ground from switch to the same ground my sub uses; power from lights to 12v source (+ side battery). My problem is when I put the fuses/relay in the lights come on but won't shut off, the switch does nothing. The little led in the switch lit up but it would not control the lights. After a couple tries of rewiring the switch now nothing works. I think I burned out the switch as all the fuses look intact. While I was playing around I did accidentally reverse the ground and supply wires do I think that's what burned it out. I'm gonna get a new switch in the morning but what are yalls thoughts??

If it came with a relay the load should not be going through the switch, only the control circuit. The load should be fused from battery to pin 30. Pin 87 out to lights. Pin 86 to ground. Fused 12V to switch. Other side of switch to pin 85. Like this...



If you ran the load through the switch you probably fried it.

This is how I wired everything according to their instructions.

What are those hand drawn lines? They used a poor choice of labeling calling the switch output the "load" but everything looks correct except for the lights themselves. It's hard to tell from the small picture but the relay appears to have a pin 87 and pin 87a. You want to feed both lights from pin 87. When you turn off the switch, the relay connects to pin 87a so you can't connect the lights to that or they will always be on. Connect the light grounds to the chassis or battery negative. If you have one light positive connected to pin 87 and the other light positive connected to pin 87a, then 1 light will be on with the switch on and the other light will be on with the switch off.

So should I pull apart the relay and see if the lights are wired in wrong?

Did you connect one of them to the middle pin? Is 1 on with the switch off and the other on with the switch on? Did you run the light grounds back to the relay? That's what the hand drawn lines make it look like. You shouldn't have to take apart the relay if you mean unwire everything. Can you take a picture of how you have the relay wired meaning show the pins in the picture? If you have a pin 87a then NOTHING SHOULD BE CONNECTED TO THAT PIN.

I connected the "load" wire from the middle tab on the switch to the relay. Everything came pre-wired so all I had to do was connect the wires to the switch and plug in the quick disconnects to the lights. When everything was connected both lights come on. The problem is they stay on regardless of what position the switch is in.

I found a schematic that appears to be from the same manufacturer. It has no pin 87a but the wiring is identical as far as pin numbers. Again, nothing should be connected to pin 87a. Do you have only 4 wires going to the relay or 5?



If both lights are coming on and not shutting off that sounds like you have both lights connected to pin 87a and the switch wired wrong.

These are what were provided. It looks like the ground from the lights gets spliced into one wire that goes to the relay.

The yellow goes from relay to battery.
The black and red are from the lights.
The green is the "load" from switch to relay.
