Look at the hub assembly currently on your truck....the 4WABS hub assembly will have a pigtail coming off of it with a connector the runs up to the frame rail. This is an abs speed sensor that is built in. For RABS vehicles (Rear wheel abs, not front), the hub assembly doesnt have any wires of any sort on the hub assembly at all.
