Gauge Installation on a 6.6L Duramax

Place the gauge mount over the factory pillar.  It will eventually be attached on top of it with 4 push pun fasteners.  Mark locations to run the gauge wires and boost gauge tubing.  Mark your holes on the low side of each gauge cup so that the wires wont have to bend upward to exit the pillar.  They will be directed down the pillar, so keeping the holes toward the bottom will give them a straighter run. NOTE: There will be a part of the factory A-pillar that will show closest to the weather-strip molding. This is intentional. Do not attempt to remove the weather-strip molding. It is glued in place.
