808 PN switch input

Can someone just confirm with an 808 with $12p. The Park Neutral input at pin B10 should be earthed when in park and left open circuit when in drive. Or have I wired it up backwards?
Also if using a manual trans does it matter if this is left earthed all the time?
Thanks

Hook it to the feed from the start relay to the neutral switch

when the pin is grounded the engine will crank, so in a manual its always grounded, and in auto its grounded in park and neutral.

In a manual the pin is left open circuit. The ECU code defaults to manual, but if a ground is present (when in park or neutral, so when cranking) it changes to auto.

That's what I thought as everything I make an auto trans patch harness conversion to a T5 one I always end up removing one of the black wires and pin from the connector, copying from a genuine T5 patch.

It doesn't, like many of the diagrams there is mistakes or discrepancies here and there to the real wiring I have found, especially VN era diagrams.

If I recall correctly I had to change the VN harness (factory manual) when I swapped to $12P, it was the exact reverse. Maybe where the diagram comes from.
