I am installing a Navigation system in my 96 Chevy Suburban.(350)
The system requires a connection to the Vehicle Speed Sensor.(VSS)
I believe I have identified the correct wire under the hood, it is purple and white and is called VSS signal in the schematics I have. It is part of the big batch of cables running to/from the VCM.(computer)
Additionally, the schematics show a dark green and white wire running to the radio from the Vehicle Speed Sensor Buffer.
Has anyone done this or have any helpful tips on hooking up to the VSS?
Will the dark green and white wire work? Assuming it is actually there. I have not pulled the old radio yet, still doing homework.
Again, thanks for any tips.

Navigation install update
For those interested, the system is installed and working, sort of.
I think the color coded wires are a bit off. I woke up today with a low battery. It was down @ 11 volts.
I think the constant and the switched power are reversed.
According to the12volt.com, the constant is orange and the switched is yellow.
That is not how I hooked it up. The JVC yellow is constant and the red is switched. That is also what the Crutchfield GM adapter calls for.
My manual is at home, is anyone able to confirm the 96 Suburban color code?
Other than that, three other connections had to be made for the navigation to work. A connection to the VSS, the emergency brake switch and the reverse signal (tail light). No problem.
The Suburban had enough juice to start and drive the 2 minutes to a train station today. Hopefully it will start tonight as I did not have time to let it charge more.
(Optima Yellow Top and high output alternator.)
