I have an 03 HO 4x4 Quad cab 204k miles on it. The wiring plug on the rear axle speed sensor is broken. The sensor is ok, but the wire and plug going to it is messed up. anyone have the part # for it. I ordered one from Rock Auto and it wasn't the right thing. It will not stay plugged in. This is the one on top in the center of the differential. I believe it is only for the anti lock brakes. Speedometer is still working fine. I just get the red brake warning light and the antilock warning light.
