DIY: VSS speed sensor replacement

[1993CivicVX]

I bought a VSS speed sensor (I realize that's redundant, but just to be clear!) on eBay for a pittance and am calling on the expertise of this fine forum for help locating the VSS on my car, removing the old one and installin da new one. My more mechanically inclined than I friend who helped me do the brakes (I actually helped him do them, as he did most of the work) doesn't feel confident relying on the Haynes manual alone, but I think between the manual and the fantastic people on this forum we should be able to wrangle the job.

Thanks as always.
