So, you'll be needing some Ampseal connectors. Please note that ground pins of 4,21,23 are common and shared, thus they can be interchanged.
| Component | Pin | Description |
|---|---|---|
| Battery + | 22 | +12v in, use the appropriate fuse! |
| Battery - | 23 (4,21) | Ground |
| WAS 5V | 1 | 5V output for Wheel Angle Sensor |
| WAS GND | 4 (21,23) | Ground for WAS |
| WAS Low | 3 | Used for the Differential setup in AgOpenGPS |
| WAS High | 2 | Used for Single with GND and Differential with WAS Low |
| Steerswitch | 8 | Can be used with a switch or a button to have a physical button to enable / disable autosteer. Basically it allows to disable the steering. Has to be connected to ground. (4,21,23) |
