The only solid green wire inside the wiring box would be for the tach
signal. I'd guess you are seeing the blue/green wires for the coolant
level switch. What colors are the wires on either side of the one you
saw as green? VW used the same basic pins and colors for all the
Vanagons so if you have a later one to look at you can see where the
green wire should be on the round 7 pin.
