I am wiring a set of offroad lights and have the wires in the engine compartment. I need to run a couple wires to switches in the cab. Where does everyone run their wires to get behind the dash? Is there existing holes in the firewall that work? Any help is appreciated. Thanks

 

There is a set of 6 "blunt cut" wires capped off with shrink tube behind the battery under the hood and tucked up under the dash by the steering column. They are there for the OEM light kits, but you can use them however you want.
