Lets see how good u guys are.
This is a segment of a part from my 924 or 931.
Anybody know what it is? I dont think it's that hard but then again I took the picture. if nobody guesses I'll post a little more of the picture.

Well, it looks like a coaxial cable terminal cover or maybe more than just a cover in that it forms a connection between the center conductor and outer shield/ground. -And it's outside of the passenger compartment, based on the water drops.
Whatever it is, my car doesn't have one (or doesn't have one exactly like it)..

That's not a coax connector -- we have those here where I work all over the place.

It's a millitary connector, and they range from as few as 3 to on the order of 60 or so contacts from what I've seen lying around here.

We use them on train electronics -- though they're referred to as millitary connectors, they are used elsewhere.

I've never seen that on my car either. It's possible the outside of this cover might be shared between electronic connectors and some other cover though.

Does look like a BNC coax fitting but more likely a cap rather than a connector.

My guess is a cap on your air conditioner system charge/test valves.

I know I have seen that connector on a 931 before, though exactly where I cannot recall,

though that box appears to do with the ign system, and that would be a test port with an electrical pinout on it.

DITC component that sits on inside front headlight pocket/driver's side? Can't recall exactly what it's called. Kinda late...

those are definitely bayonet nut connectors , (or BNC's) with terminator caps on them. they are used most commonly for video feeds, but can be used in many other applications where a locking connection is needed. the terminator caps loop the signal in most cases, but not always.
ive seen them used on radio signal amplifiers, as oscilloscope connection ports, and a host of other things besides video, even clocks.

whatever it is, i haven't found it on my 82...

OK, I found it now.

How come yours is blanked off?
Mine is connected to the oscillating sprocket valve.
Doesn`t your car have one?

Um, no Porsche left Stuttgart with that cheap keychain material dangling from it.

I'm going with Fetzer valve. Those connectors hold the ball bearings in.
Judging by the gunk on it, you should clean it with some 3-in-1 oil and some gauze pads.

It's a modified ignition ECU with a pair of BNC connectors (with dust-caps fitted), most commonly used in coax networking installations, also find common use in RF and video applications.

One other common use of BNC connectors is as input connectors to oscilloscopes; so I'm guessing that's their purpose here: to allow someone to hook up a 'scope to monitor the ignition pulses. I'd guess one's connected to the signal from the distributor and one's the ECU output to the coil.

Am I right?
