If the 3-way switches work properly, connect the black and red of one cable to one side of the 4-way switch and connect the black and red of the other cable to the other side of the 4-way switch. It doesn't matter which wire goes where as long as the black and red of one cable is connected to one side of the switch and the black and red of the other cable are attached to the other side of the 4-way switch.

OK -- So I cleaned up the wires a bit -- shortened all the slack etc.

In THIS switch box:
The Breaker to the 2 [unrelated] 3-way switches on the left is currently OFF and the switches themselves are "off"

The 4-way switch -- I connected the 2 reds and the 2 blacks like you said -- put that breaker back on - and the light works. I located the other switch that turns this same light on/off and it works fine.

All the other lights on the same circuit are working AOK

****

Now - I am just a little confused about the next part -- because like I mentioned - I mixed up which red/black PAIR was on the LEFT and which red/black PAIR was on the RIGHT

Are you saying it doesn't matter which red/black combo goes to left and which combo goes on right ?

Or do I need to determine what the original pairing of each is first?

If so... how do I do that? [i think you explained this already - but I want to be sure]

That is correct. It doesn't matter which wire goes where as long as one pair of black and red wires (the black and red wire from one cable) goes on one side of the switch and the other pair (a black and red wire from the other cable) goes on the other side.

The black from one cable can go to the top terminal and the red of that cable to the bottom terminal or the red can go to the top terminal and the black to the bottom terminal.

Same thing for the other cable (what you are calling a pair). The two pairs do not have to match. The black from one cable can go to the top terminal on one side and the red of the other cable can go to the top terminal on the other side.


Only thing that matters is that the two wires of a cable (a pair) go to the same side of the switch.

Yes. Go do something that you really like. Something that later in life you will look back at and say "Boy, I'm glad I did that".
