VW Type 2 L-Jetronic connector pinout

A quick visual reference to the pinout (wiring) of the Electronic Control Unit (ECU) used in the 1975-1979 VW Type 2 bus, from the harness side. The ECU was at the heart of the fuel injection system Volkswagen chose to reduce emissions and for better fuel economy: Bosch's L-Jetronic.
