Gauge mountings

Hi guys,
I've seen pictures in the gallery of citys with gauges mounted in the aircon vents in the dash, just wondering what the best way of getting wires/tubing to them is?

i dont exactly remember how i did mine but it wasnt too difficult,it goes through the firewall next to the brake booster thingy,where you can access it through the fuse hole then i pulled it along through the instrument cluster and had to drill a small hole in the passenger side of the cluster and your there,i think ::)
