A buddy of mine has a cutlass with a t-56 out of a viper in it.
I got the lovely task of making the speedometer work.
Viper was the only VSS for a t-56 with 3 wires(5v,Ground,Signal)
And the Guage is a Autometer Sport-Comp.

I found the wiring diagram from the sensor to the guage, but what I have yet to figure out is how to get the correct MPH on the guage. Factory Vipers had 3.07's and im sure the cutlass is more 3.50's-3.70's.

Viper has a 10 point relector wheel.

I read about people using dracs, but could anyone on here give me more insight on whats what and what would be my best bet.


And I know its off topic, But someone could do the exact same thing in a Square, so it seems ok.
