Hi, my wife recently bought an 04 Mach and the abs light is on. I hooked it to a scanner and it couldn't even connect. The tech said there might be a blown fuse. I checked all four fuses that the owners manual lists and they all appear to be good. So I'm afraid its the module. If it is where can I get one. Ford dealer says $935
You should be able to get one from a salvage yard, as they are a fairly reliable piece. A used one would probably do just fine. I would think there should be numbers on the module, and in the interchange manuals. that will tell what modules will fit your car. Another thought is Ebay. I'm not sure as I've never really seen aftermarket companies carry those, but it might be worth looking into. Hope it helps.
