I am installing a mono headphone jack into the speaker mic of an old Motorola 2 way radio. I want the speaker to cut out when I plug in the headphone. Do I need the 2 or 3 lead jack, and how do I wire it?

I need the text of an email detailing how math has been taught over the past several decades. 70's, 80's, 90's, etc.

The info has been sent out via email chains forever and is meant as a tongue in cheek joke. Help?
