I have both the dash and the pillar mounts. I don't like the pillar gauges at all. You must refocus from the road to read them. The pod on the dash allows a quick glance to see the pointers without ever leaving the road. I have also found that on sharp, winding roads, the pillar mount obstructs some vission. Finally, the pod guages are actually easier to route the wires to than the pillar. Both methods run the wire bundle up the left side of the dash (below the pillar). The bundle then gets pushed down between the dash and the windshield out of site. Real easy.....
