I am watching the GeorgeKopf thread and did not want to jack his. I need to look at a wiring diagram and when I searched on the wiring diagrams site, 2 options came up, 74 with L jet and 74 with D jet. My 74 model year car has a date of 10/73, so which is it for me?

My FI is long gone, turned into carbs. The previous 3 or 4 owners made all of my decisions for me.

Thanks for the help.

The chassis harness is the same for a given model year, no difference whether its D-Jet or L-Jet.

The VIN number is a good start. On window trim and in frank. The paint code on the decal on the drivers door jam too but they’re often missing.

Karmann started the next year build in August, SO the 1974 model year run started then. The 1974 run should the first year of the seat belt interlock.

Also first year of the dual relay under the battery tray. Mine’s Nov 73 and early mid 74 production number.

The L-Jet was used on the 1.8 liter 914s. D-jet was used on the 2.0 914s.

D-jet used a silver "hand grenade" (MPS) with a single vacuum hose and a four-wire plug on it on the right side of the engine bay under the battery. L-jet used a "barn door" air flow meter attached to the air filter, with a quarter-circle "bump-out" on the side of it.

All good info, thank you.
