The relay in my '68  was a much smaller box with just 3 terminals. That might 
have been a midyear change, but I don't find any evidence of that. '69-70 got 
a very slightly different relay that had 4 terminals, when VW added ground 
wires for everything.

My impression of the flasher relays with lots of terminals is that this all 
happened while someone wasn't paying attention, so a WAY too 
complicated design was accepted, until a few years later, when cooler heads 
prevailed. The same thing happened with the '68-9 master cylinder, but that 
took someone thinking outside the box to make it work.

Unfortunate and silly to waste power in a resistor just so you can install 
power saving LEDs. I suspect this mod ends up using more power in the 
end, making the whole effort expensive AND pointless. Hope you didn't have 
to go down that hole.
