Thanks for the screenshot and glad to hear you could get your temperatures down at least.
There should be a larger flat ribbon cable from the keyboard and a smaller one for the keyboard light, so keep an eye out for that smaller cable.
You may want to help us confirm, but it looks like your 2 keyboard cables should go to the connectors indicated by the green squares and the smaller one will be for the keyboard light.
Good luck!
By the way your fans looked a little dusty in your picture, so you may want to clean those too if you haven't already?
