Just a couple of quick questions, I have the Rear antilock light staying on in my sons 1987 F150 4x4, Could a possible problem be the ABS speed sensor or the ABS wheel speed sensor connector? If so , Is it the plug located on the rear axle,? And is hard to get off. I tried to unplug it today with no luck, Im sure i am not doing it correctly. Is there a way to test it to be sure that this is the problem? Would advance Auto have a way to run test for codes on this old model?Thanks for all of your help, This is a great site for info
