Default Digital Dash AND Vehicle Speed Sensor AND Overdrive unit common ground?

My digital dash, VSS, and overdrive all fail and then start working again simultaneously. I'm not sure if the Overdrive would stop working because of the VSS or the dash quitting, but the fact that they all stop working and then start working again simultaneously leads me to think there's a common ground that is coming loose. Can anyone confirm this? Thanks!

well, now the dash has completely failed. I've isolated the dash as the issue, it doesn't light up when doing the bench test described by Batee.com. However, power is flowing through it when connected to battery power-just no light, no LCD, no nothing.

Ok, so I've learned that the OD won't work without the dash being on, and the Speed Sensor doesn't work without the dash either. So fixing the dash panel should fix all of these issues.
