Tach Harness for “In Dash Tach” (Lower Priced Version)
This Wire Harness is designed to hook up our Aftermarket “In Dash Tach’s”.
If you’re adding one of our “TPP” Dash Tach’s to your Skylark this is the Harness you want!
This may also be the desired Harness for the 1970 – 72 GS & GSX cars if you do not have or wish to use the Factory Tach Wiring.
Note: This Harness is lower priced than our Concours Harness because it is 1 Piece and does not have a GM style Wire Terminal for the Ignition Coil connection. Its close and works just fine but that’s why this one is lower priced!
Brown Wire plugs into the “S” terminal on the back side of the Tach and travels through the Firewall and connects to the Ignition Coil.
Red Wire plugs into the “+” terminal on the back side of the Tach and is connected to a 12 Volt “Keyed” source.

This Factory Hole is “Kitty Corner” of the Fuse Block hole and typically only found on actual GS Cars.
This hole measures 1.5″ in Diameter.
