removing hazard switch from GT6/Spitfire

[Dave Fain <kc3565l@sprintmail.com>]

Can somebody tell me how to remove the hazard warning switch that sits between 
the speedo and the tach on a 1973 GT6.  I removed the tach to provide access 
and I made a sketch showing where all the wires connect to it.  It looks like 
it has to be released from the back side of the dash and pushed out the front, 
but I can't see what is holding it in place.  My switch is frozen solid and I 
think it might be part of the problem with my turn signals not working.  
thanks,
Dave
