Once you've programmed the RPM points, that's pretty much it. Just remember that the dark blue wire when activated with 12 volts, will arm that circuit. When the voltage is released (trans brake), the shift light will know that the vehicle has launched and will then activate at the first RPM. Once the vehicle shifts, the unit will see the RPM drop, and the shift light will know that it is in second gear, and so on.

Also, the shift light wire (yellow) provides a ground, and not voltage.

Hope that helps.
