9000 Speedometer pinouts?

[99Super]

Does anyone have them?
I'm trying to get speed into my T5/OBDII.
I have the sender and speedo, but I don't have the wiring diagram for the speedo.

does this thread help?

Thanks Seth. That didn't really help. The best I found so far was the discussion somewhere here (Hutch? Luke?) that said that the top two isolated pins are the inputs, then its positive to the top pin, output to T5 on the center pin and ground to the bottom pin.

I have a 9000 speedo to play with, but if that doesn't work, this is the route:

Looks like it could be handy for installing a tach in the E350 too.

Thanks Seth! Interesting website.
That confirms what I read here.
I'll tear into it next when I'm back in town and let you know if it works out.
I know I started on this several years ago when I first started my T5.2, but abandoned it when the 9000 speedo wouldn't fit in the 99 location.
Now, with OBDII support, I can build a full digital dash and not worry about an analog dial.

Just a quick update on this, I wired it as I stated above and it's working great. Both the speedo and the OBDII signal.
