For what it is worth, BOTH "AFC L-jetronic" AND "EFI D-jetronic"
fuel injection systems were fitted to 1974 model VW 412 vehicles
destined for the USA/CDN markets.

For the US/CDN market VW did switch to AFC L-jetronic fuel
injection for the final 1974 model year of VW412 four-door sedans
and two-door wagons.  And, this came with the 1.8 litre EC series
engine and automatic transmission only.

However, for the few two-door sedans sold in USA for the 1974
model year, the transmission was manual only, the engine was a
1.7 litre EA series and came with EFI D-jetronic fuel injection.
