Tach Dash Installation/Rebuild FAQ

[72BlckButy]

This thread has been created to assist those contemplating the installation of a tach dash in their blazer, suburban or truck. Many of the same processes are used regardless if your truck was initially built with a tach, so if you are refreshing your original tach dash, simply skip a few posts and pick up where needed.

The process described below was used when adding a tach to a truck which did not include one originally.

Items needed:

Paint:
Valspar Flat Clear - Gauge Tins
Valspar Flat White - Gauge Tins
Valspar Semi Gloss Black - Gauge Tins
Valspar Summer Leaf (Satin) - Gauge Tins
Model Master Huggar Orange - Gauge Needles

Parts:
Dash Bezel
Front/Rear Tach Tin
Gauges (Ammeter, Fuel, Oil Pressure, and Speedometer)
Tachometer
Tachometer Circuit Board
Tachometer Lense
Tachometer Wiring Harness

Note: If your dash will include either an air pressure gauge, or a vacuum gauge, account for the additional pieces needed at this time. The only difference will be the added gauge and a different lense.
