Original 914/6 engine management, A couple of questions Options

[michel richard]

Please let me know if I have this right:

1) Original /6 cars came with Porsche's electronic ignition module of the time i.e. the BZK module, as opposed to only super-basic Kettering (sp?) points.

2) Fuel was carbs, of course, but there was an additional cranking enrichment which necessitated a thermotime switch, a "dashpot" on the throttle somewhere and perhaps a couple of other electrical widgets.

I'm trying to make sense of the engine wiring harness that I have, which is from a /6.

Thank you.

Yeah, there was a dashpot that attached a rod to the throttle linkage and used vaccuum from the intake manifolds. I believe that it shut off the gas on deceleration if I remember correctly, you probably won't find any cars actually using this feature these days.

Porsche calls this a vacuum box in their parts book (901.113.309.00), and it appears to have two wires connected to it.

The other sensors, etc. are pretty much the same as an early 911 engine. Good Luck!
