Anyone identify this 4L60-e VSS for me?

[Lawrence]

I bought what was allegedly a '94 Camaro trans, which is now fitted on the back of the LT1 in my '55 Bel Air. When I came to connect the VSS, it was on the wrong side and in a different place to the other one I have. I swapped the plug over as it was different too, but I'm getting a very low speed according to the PCM (only got up to 8 mph at about 5000rpm with the car on stands, rear end ratio has been corrected) so the PCM won't shift up. Any ideas what it's out of and how many pulses it should be? (Oh and dont worry about the yoke, it's not pushed in all the way in the pic!)
