I've installed some KC Flex ditch lights on my '19 4Runner. Instead of using their included rocker switch, I purchased a CH4x4 switch. I also purchased a wiring harness that included a relay. The harness also included a switch, that I cut off.

The relay has a red/black/yellow wires going to the switch. My CH4x4 switch has 2 red, 1 green, 1 black wire. Can someone give some direction to which color switch wires, go with with which color wire on the harness. I found some people wiring the (2) red switch wires together which will enable the switch to come on when the lights are activated. But I'm lost as to which wires to match up on the harness.

Any help would be greatly appreciated. Thank you!!

I've attached an image of what I have.

any harness can have any color wires. so you need to either find the harness diagram or get a test light and start figuring out what does what. You can hook it all up and start connecting wires to see what does what. you may or may not pop a fuse lol..or start a fire.

Thanks for the info! Unfortunately the harness does have a diagram but it doesn't specify what the different color wires are for the switch because the switch is part of the harness. I cut that switch off.

Makes sense...i did the "might start a fire" method

That looks to be a standard 5 pin relay. Look up what each pin is supposed to do and trace the wires from those pins. Easy stuff

Perfect - Thank You!!
