Tach Harness for “In Dash Tach” (Concours Level)
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 one features the correct GM Ignition Coil – Wire Terminal and features the Junction that connects both halves together like the Factory Harness. If you don’t need our Concours Level Harness we do have a lower priced version that will work just fine.
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 harness is offered with or without a Factory Style Grommet
The Photo below shows the factory Tach Grommet location. (Red Circle)
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.
