Connecting power connector I connected the red and white wires but I also have a green

I connected the green to a “com” connection but that didn’t work

It's best not to guess if they don't have labels, as that could damage your system.

The following help article and compatibility checker can help you here:

I'd also recommend checking your system’s manual, contact a local pro, or look at your system’s control board.
