I moved into my house about 8 years ago and it was new construction. A couple of years into it, I switched 2 garage lights to ceiling fans (with light) but now I want to switch them back to the original fixtures. Unfortunately, I've lost the original diagram I made showing me how it was all wired together.

The garage has the following:
2 x inside lights
1 x outside light
2 x switches
switch #1 is inside the house and has 3 x buttons (controlling lights in the kitchen/mud-room/garage)
switch #2 is inside the garage and has 2 x buttons (controlling garage and outside light)
4 x power outlets

Not including ground, the wiring from the ceiling is:

* for lighting fixture #1
1 x cable with black and white wires
2 x cables with black, white and red wires (the black wires are already twisted together)

* for lighting fixture #2
1 x cable with black and white wires
1 x cable with black, white and red wires

The fixtures themselves have 1 x black and 1 x white wire

Any advice on how to wire this all back together?

I do have a multimeter, but I'm a real beginner and would need *basic* directions

Thanks
