Well there is a larger flat plug which points straight down on the back side of the throttle body. I felt back there and whatever its plugging into did feel plastic but I could only feel one screw since it was such a tight area. Looks like it would be no fun trying to get it out. I called around to all the auto parts stores in my area and no one pulls codes so thats not an option unless I care to purchase a code reader. It would be nice if there was a way to tell if the TPS is working or out of wack with something like a volt tester.
