Im wondering where i can find the VSS wire on my 94? I have a in dash nav system im getting and it needs that wire to function correctly. Thanks!

 

The VSS is located on the tailshaft housing of your tranny, driver's side. The signal wires run to PCM terminals:

-Yellow signal wire = pin A32
-Purple ground wire = pin A31

 

Thanks Injuneer!
Any idea why a GPS would need something like that if its supposed to be tracking 3 satellites at once anyways? ... Maybe it has something to do with the rare event that you enter an area and it cant reach the satellites... hmm
