Autometer VSS factory PCM

I need some wiring help for my VSS. I have an autometer sender for my Super T10 trans, I want to hook it up to the factory PCM (2000 Fbody) The wires indicate VSS hi and VSS lo (pins 20 and 21) For the auto meter sender, it specifies ground, Ign and signal. So, how should I hook this up? Neither of the two vss wires from the pcm are ign, but I have a souce from the lockout wires in the same harness. Where does the PCM then run the speedo from the output?

That's what I would have thought, but I didn't get any voltage on my test light when I turned on the ign. Only from the pink wire going to the reverse lockout.

It sounds like a 3 wire VSS. It sends the wrong signal for the ecu to recognize. You need a 2 wire that sends a sine wave signal for the ecu.
Dakota digital sells a pass thru to hook to the T10 speedo output.
