3. Crank (or run) the engine for a few seconds, until you see a trace appear on the screen in TunerStudio, then release the starter.
4. Determine which of the below images matches your trigger pattern:
#### Correct missing tooth shape
#### This is the correct missing tooth shape:

#### Swap your wires!
#### This is the wrong missing tooth shape - swap your wires:

> These images were collected on a Volvo 60-2 trigger wheel, the exact timing may vary, but a long period of low preceding the long high time (marked with arrow on the wrong image) is the clear indicator of a miswired sensor.
> These images were collected on a Volvo 60-2 trigger wheel, the exact timing may vary, but a long period of low preceding the long high time (marked with arrow on the wrong image) is the clear indicator of a miswired sensor. The correct pattern is equally sized low periods, with a single long high period.
5. If your missing tooth looks like the wrong example, swap the VR+ and VR- wires. Repeat steps 2-4, and double check that it now looks like the good example.
6. In TunerStudio, ensure that "Use only rising edge" is set to `true`, and "Invert Primary" is set to `false`. (found in the menu *Base Engine* > *Trigger*). These are the only correct options for a MAX992x-based VR interface.
