(+) VSS Signal Wire

[AirNWater]

Can anyone tell me which of the 2 VSS wires is the Positive Signal Wire on a 94 Ranger 3.0L? The drawing I have has a Gry/Blk wire from the PCM (pin 3) and a Pnk/Org wire (Pin 6). It looks like the Pnk/Org wire is connected to a ground ( the drawing has a dot in the middle of the line, but all the other ground symbols have the typical ground lines (3 horizontal lines) under the dot), but I can't be certain.

Yes, Gray/black is the "+" and runs to cruise control amplifier pin 3

Pink is the ground and runs to pin 2, it is also externally grounded via a splice

1994 was the last year of speedometer cable, VSS is just used for cruise control although computer also got the VSS signal.
On the computer it was pin 3 "+"
Pin 6 "-"
