Got a message from our friend Christoph/ cs-werke that he has reproduced the orange cap that many of us miss. Most are broken and at best, beat up.
He has them in both sizes, for the 6 (14€) and 9 pins (16€). Plus shipping.
Cheers

He is doin’ it right!
And both sizes too. Very cool. Some jewelery for the engine compartment. I know you need them......

Seems to be missing the attachment tail though?
Another part that I didn't realize I needed until now. 
I see that my '73 has a 9 pin port. Does anyone know when it switched from 6 to 9?
Thanks for posting! If anyone is interested in a group buy to get a few of these to the states, I'd be interested (in either participating or helping organize).

The 9 pin is near the brake fluid reservoir and the 6 pin above the thermostat. I’ve never had the 6 pin and can’t answer the separate functions. Seen them on both carb and FI cars as in the pics
I have one by the brake fluid reservoir but I've not seen one over by the distributor, anyone have a close up of that location? The original spark plug harness used to have a wire that went to the diagnostic port by the brake fluid.

The wiring and plug/cover by the distributor often gets "lost" during an overhaul!
What specific info is sent through those ports? And is there an adapter that can be hooked up to it so you can read that info on a laptop or an iPhone?
Best pictures I've got on me. (No judging--I've cleaned a lot since then and repainted the mount, etc.)
My goodness Jay, no judgement to be made. Compared to my engine, I would eat off yours.
Great pic of the distributor location, too!Now I am so curious what these ports lead to/from. I will have to investigate my car and/or wiring diagram...
The port has connections for rpm, dwell, engage starter, volts, not sure anything else. Its on the wiring diagram if you look closely. There is someone on 2002faq that made a 4 cylinder device, i think he offeres one for m30's not sure.

I have the 2002 Tune Box, very cool. I can start the car remotely and check dwell, rpm and voltage.
I also have the 2002 tune box. Will it work on my 3.0 cs?
Sorry to ressurect an old thread, but does anyone have or can send me close up pics or describe/diagram showing how the wiring of this thermostat housing diagnstic plug apparatus hooks up to the ignition system/wiring harness? Thanks.
Steve, You need the large coil cap which has wire in it as well.
I still need this piece, which slides over #1 spark plug wire if anyone has one lying around for cash money
It does work on the M30s and it also can be connected to an AFR signal.
