Where is the speed sensor on a Speedo?

There are three wires attached to the back of the speedo which I assume are part of the after-market immobiliser. These wires run to a small black box and a further wire runs from this box to the loom. At the loom I found two wires had been cut, soldered together and joined to a fourth wire leading to this little black box.
