under the dash drivers side you will find a plastic flap with a resistor in it open that and you will see the OBD port

I found this on a google search.
"I will check my car, but I would think it is stock. A couple of pins get jumped in three different ways, this sets the priority and some speed functions different in the DME. They have to do with sending data to the OBD port.
You won't notice any difference driving with it open unless the DME got very busy with data. Sorry don't remember much more but the three states are part of OBDII legislation so it you want more look it up.
Edit should mention the three ways. Closed all priority goes to the DME running functions.
Open makes the car report to itself more often and changes the priority of sending logged data. On our cars the report frequency is more than doubled, so because of the work load that means the DME has half the computing power.
Plugged in scanner is the same as open but the OEM can now have the OBD port behave with extra functions. The basic OBDII functions must be present but other things can happen. IE the ability to re-flash."
