I'm was swapping the the head light switch from a 73 to 74, and there is one less terminal on the 74 switch. I guess I have to trace the diagrams to figure out what is left out..unless someone happens to know...
got a laugh as I looked up the price for the little switch on pelican..it's $433, which is more than I paid for the car!!
not as easy as I hoped, there are several wires left over from the dash panel swap too.
