Here you go...

PIN Number 64 is engine speed output. Should be a blue wire with a green stripe. Here is a picture with PIN numbers, this is looking at the connector from the wire side.

OK thank you for the info!!! I already tried this but I think I had the wrong wire. It was a light green, not blue with green stripe.

I asked the same question a few weeks ago.
On my car, which is probably a very different layout, it's a red wire going into the gauge cluster, pin #21 on the left hand side.
