- Grey — Relay ground return
- Red — Relay input 1
- Pink — Relay output 1
- * — Relay
- ** — Switch
- Yellow — Audio ground return
- Brown — Audio input
- Green — Audio output
Note: The 12 V connection can be used to energize a relay coil with up to 50 mA. If more than 50 mA is required, an external power supply up to 25 VDC at 120 mA can be used.
