Aim RPM Coil Adapter Inductive has been designed for installation on single-cylinder 2 or 4 strokes engines. It is a filter that converts RPM signal sampled by induction from the spark plug in a square wave signal. Images here below show the signal sampled by induction on the left and the square wave signal on the right.

To install the adapter connect the plastic clip to the spark plug and the cables as follows:
- the black cable labelled "GND" to the device GND pin • the red cable labelled "9-15 VDC" to a +12V output (the battery positive pole for example)
