If that mic uses a quarter inch stereo plug, wiring is simple. The short contact is the push to talk lead (most likely red), the next longest is the audio (white), and the very long one is ground (shield). Might have to solder the black along with the shield to that long contact.
 
Got it! Thanks Ron

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
