Please use the relay to power the lights.

^^^Read that thingy^^^

A relay is a good idea even if you get a switch to handle that kind of power because for one all that power is now inside where you are at (bad cause harm will probably come to you or any of your electronic equipment if it fails) With a low power switch and a little 22awg wire your not gonna harm anything. Plus with a relay there is less resistance (not that there is that much anyways.) and a shorter path for the power to go directly to the lights instead of into the cab through a switch and all the way back out into the lights.

I run relays on all my lights, I even did the relay set up for my regular headlights and there is such a difference! Not to mention with a relay and a switch you can keep the switch on and have the lights come on when you flip on your highs.

My credo
Perfection is worth the wait
use a relay or burn up your wiring. your choice.

Tie the trigger wire for the relay into the 12v + wire of your high beams. Then use the switch so control your ground so you can still manually turn off the fog lamps with your high beams on.

Theres a thing about it in the tech section. But yeah basically there are connectors that "passively" splice in with the high beam wire going to one light. You connect a small wire from the high beam using one of those connectors run that wire to the switch inside the cab. then the other wire off the switch back to the relay I think its pin 85 then run a ground to pin 86. Pin 30 is your power from the battery, pin(s) 87 you run to your lights then ground the lights somewhere (preferably the neg batt terminal).

If you go to napa or somewhere get 2 relays with 5 pins as these will have 2 87 pins. Tell the people at the counter what you are using them for because apparently there are 2 different versions of these.
