Stick the + "needle" from the voltmeter into the back of the plastic connector until it touchs the pin and then touch the other one to a ground.
Have you tried datalogging on analog 2 yet, that would be a quick elimination for us.
were you selecting other PIDs other than just analog 1 when you were first trying it out. I did that and noticed that it didn't work, so I selected just one more PID(I think it was MAF voltage) and then I got the analog readings. Apparently you need to have a common PID and not just analog ones in order to recieve info from the sct.
BTW, google mapped where you are and it is 5 hrs from here. There for a little bit I thought it would be faster to drive down there. Hope you get everything going and get it back on the road soon!
