My outer switch box has a wire coming in from the right hand side attaching to the 3rd from the bottom pin with a green and white wire from the left. I have found no mercury wiring diagram with any wire except the single green and white connected. Picture of switch box attached - any ideas or solutions appreciated.20210113_122541.jpg
