swap harness pin question

hey all,

just a question about the vss wires on green connector pins 20 and 21. which wire would a person connect to a Dakota digital 128,000 pulse generator? sen-01-128 instructions have three wires red(power for the sensor) black(ground) and white which speed input to pcm. which wire does it go to, pin 20 is low signal and pin 21 is high signal according to the pinout from lt1swap. thanks for any input.

Chip

Re: swap harness pin question

I dont think high and low make any difference in a VSS signal. The low is a ground signal and high is the sensor signal so I would go with the high.
