Next is to check power at the VSS with the key on you should see:
Blue ECU pin47 = Signal
Brn/Red ECU pin 4 = Ground
Wht/Blk ECU pin 7 = 8VDC power
The output/signal is a square wave and is difficult to check with a digital multimeter but not impossible. If you read the 8vdc on the sensor connector next back probe the signal pin in the connector and hook one meter lead to the pin and the other to a ground wire hooked up to chasis. Set your meter up to read Vdc. Very very slowly turn the gear and watch for the pulsing on the voltage readings on the meter.
