The switches come with an insulating Kapton seal on them that must be removed before the switches can be adjusted. If not adjusting filter this tape should be left in place.

Recommended values for the filters are shown below (By default both switches will be in the On position):

If you wish to use an external MAP sensor located in the engine bay, this switch should be to to `Ext.` and the sensors signal line should be connected to pin `C8` on the Black connector. The MAP card can be left in place or removed when the `Ext.` option is used.
### Stepper Driver
By default the Dropbear unit is designed for use with PWM idle valves, however an optional stepper motor driver can be fitted.
> Please note that using the stepper driver requires pins C3 through C6 on the grey connector. Other output functions cannot use these pins when a stepper driver is installed
{.is-warning}
The board has a socket to install a standard DRV8825 stepper motor driver if required. It should be installed in the following orientation if needed:

## Pin out
The Dropbear ECU uses 2x 24 pin Delphi Sicma connectors. The connectors are keyed and will only connect to the matching colour loom plug.
