/6 wired goodies, What don't I need? Options

[Dr Evil]

I am figuring out my /6 wiring and can not find the diagrams for the following items:
RPM sensor
RPM transducer
Radio noise supressor

Can I use the regulator on the /4 board?

All of these were originally on the console in the back of the 911. I am keeping the CIS if that matters. Do I need to keep these items? How did you/would you do it?

Thanks

first thing i'd check is to see if the alternator from the 911 is an internally regulated one; somewhere in the SC days they made that change. if that'd the case, you don't need either regulator, and i'm not quite sure what you do for the front alternator light (Terminal #61?). (i'm replacing my alternator with an internally regulated one and i need the answer to that question too...)

the radio suppressor - IIRC the original /6 had that too, so you should be able to find it on the /6 wiring diagram - you have the Art Zapf 914.6 digram, yes? well worth the money.

the other parts have names similar to the early MFI cars - one was the tach adapter, a ballast used to create enough current thatthe original Kettering tach could be used after the change to CDI. (Root-Works just went through that process and there was a thread not that long ago...) the other was a part used to control the overrun cutoff solenoid (specifically, it was to release it when the rpm dropped under 1500 rpm.)

the CIS cars use a clock (tach...) triggered fuel pump relay, so you'll need to provide an ignition signal to either that relay or the CIS mini-brain, whichever you have for your year car.

the last time i did an engine transplant between two CIS cars i pretty much needed the wiring diagrams of both cars to see what needed to match up with what.

good luck !
