Not sure what this goes to but when I bought my DA last march I noticed it and havent found any listing of what it is used for, I have a 90 GS btw.

 

Is this pic taken on driver or passenger side ?

 

passenger side of the car

 

OBD plug. 94

 

really even tho my car is ODB0? I can turn the key to on and watch the ecu blink for engine codes without the pin method

 

Better known as the Service Check Connector. 94

 

The pre-'92 DA does NOT use the Service Check connector for reading ECU error codes.

The pre-'92 DA uses the Service Check Connector only for locking ignition-timing down to base before setting distributor position.

 

thats cool to finally know where do i get one of those and info on how to use it haha

 

Get WHAT? You don't need anything for reading codes on your car.

 

You need part number 525881/72377

Simply unfold the device and insert it into the service connector. Start the car and set the base ignition timing using a timing light

 

Or you can just use an opened paper clip. That's all I ever used for 22 years.

 

Tegger, I was obviously talking about using it for timing not for reading the codes I already said I knew about counting the light flashes...

 

I was talking only about shorting the Service Check connector, regardless of any reason why you'd do that.

You do not need any special tool to short the connector, even though one is available. All you need is a paper clip.

 

Google the part number

 

I've been had! I never actually looked it up, not suspecting you might have been pulling a joke!
