unknown connector????where to plug it!!!
 

Hello

I'm little lost here , few days ago i swapped the motor in my 924 and ( new donor came from 87 944) and next to the firewall ,on the back of the engine head is unused connector .Its a 3 lead round connector attached to the rear engine lift point. Its similar in look to the o2 sensor plug . I don't see where it should be plug too. I'm little lost , i don't have diagrams neither manual .. did some search but not much luck . Thank you in advanced .

Its a connector for the TDC sensor that was used back in the 80s with a shop oscilloscope. Ignore it (unless you have a large shop oscilloscope and need a trigger signal.)

thank you much sir. Not planning to analyze it with oscilloscope:) hehe . Thank you for help
