Tachometer questions....again

I would like to permanently attach a tach to my Rebel. I have reviewed a whole bunch of post and I am stumped on where to connect it. A picture of an exact location or of how and where someone connected it would be great, but I never found one.
I read one forum with a Vague mention of the Bu/Y wire and a wiring diagram that looks like it comes off the ignition control Module. and just to be sure I am attaching my first pic. Is that the ignition control module? the second is the wiring Diagram and I circled the only Bu/y wire I could find and it just does not look right to me seeing it in the Diagram
I have also read some threads that said they attached it to one of the coils. I am attaching another picture of the same Diagram and I am wondering would you get into them before or after they split?
Then the Third Option someone said they just attached to the yellow one....there are three.... they go thru a plug before going to what I believe is the ignition control module.
I really do try and find the answers looking through years of past threads but I end up with more questions and hoping for a photo. I have a picture of the yellow wires before and after the plug if anyone would like to see those.

No that isn't the ignition control module which we tend to call the CDI (capacitive discharge ignition) module
Blue/Yellow circuit is found on 4 circuit CDI connector, your image is of the three Yellow regulator/rectifier alternator circuits..
Just behind the coils and regulator/rectifier is CDI hanging from frame
You can see the three yellow alternator wires to the left of CDI module in this image..
