Plug for small X11 diagnostic socket?
 

G'day Folks,

I'm about to try and set the ignition on my W201 correctly in accordance with chapter 15-515 in the FSM. I need to mess about with an oscilloscope to do this correctly.

I'd like to make a connection between the small X11 port shown in the following pictures...

...with my oscilloscope that has BNC connectors.

Where can I find a plug that will go into the socket so I can wire away to my heart's content?

I'd rather have a solid (reliable) plug than be messing about with scope / multimeter probes.

The FSM under Engine/CIS-E/Testing CIS-E components has in that document part numbers for special test equipment - and that includes testers which have such a connector attached.

Then a search on google usually yields a few of those gizmos on ebay. You could then chop off the connector or sounding like you are an electronics type, maybe cut the cable, add a new type connector between the test gizmo and the X11 connector, then also be able to reconnect it and use the test gizmo too!

Thanks I got some numbers from the FSM but the pictures are really unclear (on the CD version of the FSM on www.startekinfo.com) so I'm not sure if either of these test cables would be good

For years I just used the standard 2.5 mm pins that are used all over the car to make individual test leads with a small piece of heat shrink over them.
I then got around to making up a proper test lead with a plug from an older Diesel tach amplifier which plugs into that socket. There are many defective ones around out there. I removed and tossed the circuit board, connected my wires and added a strain relief. Works great.

Thanks Rick

(Damn and drat - OM617 tachometers are not common over here - very hard to find that plug - I do have one in the garage somewhere however)

Since you want this for testing and not permanent installation.

Why not make a little PCB to hold the pins ? Shouldn't be too hard to design since all you need is the radius and angles for the pins in the existing socket.

There are services that'll make 10 pcbs up to 5cm x 5cm and route them to shape for $10 (google itead studio for example).

I'm now getting to the stage where I'm thinking there's nothing much wrong with bits of welding rod and a crocodile clip. Too much hassle looking for a plug!
