Tremec TKO600 with Autometer Electronic Speedo hookup??

Doesn't the VSS sensor create a small voltage by passing by the magnets and that is what the speedo uses to convert the pulses/mile to a measured mph?...if so I don't think the sensor isn't going to care which wire is grounded or which the speedo is reading from, just so there is a voltage difference to read as a pulse.

Correct. It's a two wire sensor, which means that the sensor is magnetic and the reluctor must be steel. I think that also means that polarity doesn't matter.
