Where can I find this?

I am looking for a OBD2 plug and at least one pin.
I am wanting to wire my scan master into this plug so
I'm forced unplug the scam master from the cars ALDL port when I'm uploading a tune.

I have read that if the scan master is connected to the PCM
when your uploading a tune your in trouble.

Re: Where can I find this?

Correct. You can't have two different devices connected to the data wire at the same time.

I ran the ScanMaster's white data wire to a micro switch mounted next to the ALDL connector, and then attached it permanently to the data wire on the back of the ALDL connector. No wire to connect or disconnect. Just a switch to interupt the ScanMaster data wire when required.

Thanks for the suggestion.
I would rather be forced to unplug it so I don't forget.
