Trying to piece together an L-Jet fuel injection system with the parts I currently have. Missing the ECU and have a 6 pin AFM. Does anybody know what the correct ECU part number is for a 6 pin AFM? The early 1974 411 has part number 022906021F and the going rate is 1/3 the price of a 1975 914 unit, part number 022906021G. A 1975 bus ECU typical part number is 022906021H. These are all indicated for manual trans but not sure which AFM they work with. Thanks

Thanks for the info. I know 022-906-021G is the proper ECU for a 75 l-jet that I should use but still not clear if that works with the early 6-pin AFM. Maybe I will stumble across a complete system eventually and won't have to worry about this.

Maybe I will stumble across a complete system eventually and won't have to worry about this. no mate. that is a 74 Model Year ECU part # you are quoting. the 6 pin plug goes with that ECU. the 6 pin also goes into a 74 specific AFM. the 75 model year ECU is part # 473 906 021. that goes with the 7 pin plug. the 75 AFM is also different and goes with the 7 pin. but it will work on either a 74 or a 75 1.8 so long as you have the three things lined up. the ECU, the harness connector and the AFM. |

No idea where it came from, since I had a 1970 which I converted to carbs many years ago. Anyway, it’s yours if you want it. Just let me know.  Tom |
