I am trying to install the GE Sunsmart Digital timer. I've read the instructions and tried every possible configuration...that being said, I know nothing about electrical wiring. I do know it's a 3 way circuit. The timer has multi-colored wires. I do think I am correct that the ground is connected to the green and perhaps timer white to white bundle. Beyond that I'm clueless.
attempt at attaching switch wires
Any input would help. I don't know if it is "load side" or not. There is also a separate short black wire that is separate included (I have no idea what that's for...jumper perhaps?)
