VSS for 92 silverado

I need to locate the VSS wire and the reverse wire on a 1992 Chevrolet Silverado so I can install my N2 correctly. Can anyone give me the color and location of these wires. Thanks

So according to this I dont have a VSS wire? What do I use instead? What about the Reverse? Thanks

The VSS wire is located in the electrical center on the firewall above the driver's kick panel. There is a cavity in the top left corner labeled Orange. The middle pin is the VSS connection you need. The reverse wire will be light green. You may be able to find it in the same area, but I can't remember. It will go to 12 volt + when the truck is in reverse.sparky
