Well, I did some digging and pulled what I think I need to create a VSS signal on my truck. I bought the following from Radio Shack:
276-0145 NPN infrared phototransistor
271-1120 1.5k ohm resistors
276-0143 high output infrared LED
271-152 100 ohm 1watt resistors

I plan to connect as follows in the picture, and run the wire from the phototransisor to the MPGuino. It will read signals from the LED as the driveshaft yokes spins by.
