thats always an option. i however have always been a fan of isolating aux circuits and not tapping into factory lighting systems. easier to fix problems. Plus it looks cool with all the lit up LED switches lol!

I'm not big into splicing into my factory wiring harness.

So i finally got my lights and i'm going to wire them in the next day or two. So my question now is i want to be able to turn the light on and off by a switch in the cab and not use the high/low beam switch. But i would like to have the lights only be able to come on with the ignition on, I've read that i can accomplish this by taping into the power supply for the headlights. But i would like to be able to turn my headlights off and just use the KC lights (for fog/snow) can i accomplish this by using the headlights power wire?

Oh yea if i can do what i want by using the headlight power wire which wire is it?

I used the parking light wire as the trigger wire for the relay. It's the brown wire at the back of the parking light bulb. This allows the aux lights to work only if your parking lights or headlights are on.
