You can pull the electrical connector off the connector going to the hub, and on the other end pull the large connector from the electronic brake control module (pull front left wheel and wheel liner to access EBCM) and probe for continuity. When you pull the connector off the EBCM there is a safety tab you have to pull (I think it is red) and you move the large lever to disconnect the connector. If there is a break in the wire you can run a jumper wire from the wheel speed sensor connector, across the engine and to the EBCM connector. You need an electrical diagram to know which two wires going into the EBCM connector correspond to the two wires coming from the wheel speed sensor.
