Hello - i've got a new '88 924s. I've noticed a connector with a rubber bung in at at the rear of the engine. On the eshaust side of the rocker cover. ANyone got any idea what it's for?

I believe it's for a test tool Porsche used to use at the time..... is it a round connector with five or so pins inside??

[sdelasal]

Yes - that's the one... any idea what the pics connect to or how to use the connector?

that connector was never used. it goes down to a sensor in the bell housing. I think it was something Porsche was thinking of using but never did.

I think it connects to a speed sensor for a tool that measures engine RPM for setting CO mixture... or at least that's the only thing that comes to mind.

my mistake - i just realised it's a three pin connector, male, with a rubber bung to close it off.

The connector you have is magnetic speed sensor for the tool that was used for setting CO mixture, back in the day (have also seen it on old VW's, and Audi's and MB's). The 7 pin connector (if you have one) should be on your left front fender (under the hood behind the strut mount..looking front to back).
