“North American specification, 1968~71 VW Type 2s had a weird electrical system & loom, with some equally weird switches and rear lights.”
Which switches are weird? (…asked the guy with the US Spec ‘71)
The combination, direction-indicator cum headlamp dip switch is weird, with regard to direction-indicator connections.
North American specification, 1968~79 VW Type 2s do
NOT have the headlamp flasher facility, unless someone has substituted the British & European specification, 5-terminal headlamp relay and retro-fitted a suitable red cable from terminal 30 on the fuse-box. to terminal-30 on the relay.
If your VW Type 2 is of 1971 or later model-year, you might be okay with regard to the direction-indicator flasher unit!
The USA specification, 1968~69 VW Type 2 direction-indicator flasher unit is extremely weird!
The USA specification, 1970 VW Type 2 direction-indicator flasher unit is one-year-only type, for which it might be difficult and/or expensive to find a direct replacement.

If one has a North American specification, 1968~70 VW Type 2, it would be
WISE to carry a spare direction-indicator flasher unit of the appropriate type and check to make sure that it functions properly!!!
