On my 1992 which is a 2 wheel drive the vss sensor is on the tranny towards the back. If you do a search on speedometer in this forum you should find some wiring.I have the vss wired into my 5.3 pcm and the output wired into my drac box to control my speedometer. My fuel gauge i never touched so it works fine. Not to sure how the fuel gauge works on a 1996.
