Ok so i just put fog lights on my ls. I have the dash trim piece with the fog light button and harness.

How would i run a wire from the fog light button (inside car) to the fuse box (outside the car)? I heard there is a little opening under the steering wheel that i can pass wires through?

 

ya theres actually a huge opening under the steering wheel. you have to of course slit a hole in the grommet but thats about it
