Ok. Found my spare blue ribbon foils. I'd assumed the air cooled
Vanagon blue ribbon wouldn't have a spot for a glow plug bulb. This
one does. (which makes sense given the allowance for a heater core and
radiator bracket mounting)

As I suspected, on the blue ribbon foil, 14/9 is ignition on 15
positive in. 14/12 is (I assume) ground supplied by the glow plug
relay. Those paths connect to the spot where a diesel glow plug bulb
would fit, were this foil to have one.

Got what I needed. Sorry for the fuss.

Neil.
