i got a sinlge pillar pod mount with a boost gauge, and im a bit weary about mounting it just yet untill i know what to do. should i drill a whole in the pillar or take it off, or what to run the wires? and then, how do you take off the stock pillar vinle or whatever it is if you need it off to run the stuff. also, where do you hook up the 12 v power source needed for the light? thanks.
