Red Connector Pins 20,21,50 Wiring gurus need help! The swap in question is a 84'Regal with Lq4/200r4. 2002 Camaro harness and PCM. I'm de-pinning my harness and I'm stuck with a few wires I'm unsure of. But I think I'm going to need pin 50, but I'm not so sure about pins 20 and 21??
20- vss low signal
21- vss high signal
50- vss signal <--- Is this used with aftermarket vss generator??? My plans are to use SEN-01-4160. A vss generator i found online, recommended by lt1swap.com

Pin 50 is the output from the PCM to the speedometer.
Pin 20 is the low (ground) side from the VSS
Pin 21 is the high side of the VSS, these are the inputs from the VSS to the PCM
Looks like the dakota digital sender you are looking at will work, it has the high and low output just like the factory one.
