Appendix B: Optional Breakout IO Board Connections:

Connecting the load to the High power and trigger outputs:
You may directly connect your high power DC load + & - to J5. The load is activated via fuse F1
when the output is triggered.
You may directly connect a <150mA relay coil or other low power load to the J4 & J6 connectors.
The + load terminals are always wired to VCC. The (-) terminals are connected to GND when a
vehicle is detected and the output triggered. J5 is always triggered at the same time as J6.
