B16a speed sensor for SiR cluster?

Has anyone ever wired up the electronic speed sensor on their b16 to work with the SiR cluster in a 91 hatch? I don't know where to wire the three wires to that go to the plug. please help. thanks.

what i did was converted to manual speed sensor, pretty much take the bottom half off the electronic one you have and plop it in the tranny, works pretty well, just makes sure its locked in, and it saves about 200 so you dont have to convert to manual speedo the "right way" because ive heard you gotta stick with manual speedo.
