Hello all, 1st Post. THANKS IN ADVANCE for any help & Support!

2000 Land Rover Discovery II w/LS Gen 3. Trans is 6l80E. Engine harness from PSI Conversions and Trans harness [and TCU] from Zero Gravity [ZG] .

We're stuck on the required VSS input required for the PSI Harness. We've reach out to both suppliers and still can figure out how to wire the single signal wire from the Trans [violet/white] that says "Speedo out" to the VSS sensor input [2 wires Green and Purple] on the PSI harness.

The Green wire [according to Zero Gravity] is "low reference" but we could not extract if this was "ground" or some steady voltage between 0 and 12 provided by the PCM. The Purple wire on the PSI Harness is "high signal" which we assume will be connected to the Zero Gravity "Speedo output" single wire.

Any help is greatly appreciated.
