The replacement pads for my E0 came with the sensor wires and i just cut them off. No Contours were made with sensors. Some Mondeos and Cougras had them though.
There is a real good chance that you have the wrong pads. Take a look at the illustrations at BAT
www.batinc.netThe Ford catalog is wrong. And of course, the aftermarket patterns off the factory catalog. It says the build date for the change is 5/99 but it was much earlier. Perhaps as early as 2/98 which is the date for the change from E0 to E1. It is best to check the illustrations and order accordingly. Don't cut the wires until you know for sure that you have the correct pads. The late SVT pads are the same as the non SVT pads.
