Great link Luck...I just subscribed to that thread and downloaded the PDF of the Pinout chart. I am embarassed to say that after working on this car for 10 years that I don't have a Service Manual..the reason I don't is because there are people like you on this forum.
I will fiddle around with it again and see if I can get it to work, otherwise I either will have to deal with it, by the JVC Pulse Generator, or get a new NAV unit that doesn't need a VSS to work...most likely in this order. lol
