$35 Electric Power Steering with Fail-Safe - No eBay module and no caster issues!!!

I converted my '73 Dart over to a Prius EPAS system, but it doesn't seem to be giving assist in the Fail-safe mode as you suggested. I have the box wired as you describe, but my question is, do you need the plug that runs from the box to the torque sensor on the unit plugged in to work correctly?
