Sequential Gear Shift Lights
The device is configurable via a single programming button by means of a simple learning procedure of the engine's rpm. When in programming mode, the unit displays half of what it will display after programmed. In other words, if you want the first shift light to be at 7000rpm, then you only have to hold the engine at 3500rpm while in learn mode.
Wiring is very simple with only power, ground and a tachometer pulse required.
