How to put FLASHER in?

I have a 76 Corvette, and I cannot find where the flasher goes into the dash at! Am I going to have to remove the panel with "glovebox" or...???? Help!:banghead:

i had to take my 2000 into the dealer and have them pull the dash and it cost me almost $1000. Totally different cars, but it was not easy on my C5. All the best!
