Hi Tom, I have that right , I have the B/Y wire on the negative of right coil, does it fire #2 or #3 cylinder

...l, does it fire #2 or #3 cylinder

#2 and #3 fire together. Yes, at the same time. Same thing with #1 and #4.

It's called "wasted spark ignition". Besides firing at the top of the compression stroke, the plug will also fire at the top of the exhaust stroke. There is nothing gained (or hurt) for emissions or anything like that, it's just the simplicity of having no distributor.
