Well, I reinstalled the vdo and followed the correct wiring and still no results at any speed. I did see somRFIDference to ground issue in some past posts so could this be a reason? I also saw a past reference to connecting the red wire last, assume this is the hot wire. The first time I installed the vdo I did not follow this procedure so could I have cause further damage? The original problem was the vdo worked some time but mostly I had no readings.

I am really at a loss here, appreciate any feedback.
