Where is located vehicle speed sensor on Mazda MX 6 1990?

I am not exactly sure on the 1990 model, but on 93-97 it is located on the transmission next to the firewall aprox 20 inches below the brake master cylinder. Remove the air cleaner, there is a diagonally positioned bracket w/ 2ea. 10mm bolts and a ground wire that must removed for access. It is held on by a 10mm bolt which is easily removed with a 24" extension and 10mm socket. The VSS is difficult to see and will need to be rotated w/ tools and a wire lasso to provide vertical lift. The removal process can take several hours and a great deal of patience.
