I have a new holland L553 skid steer. I had some wires come out of the plug on the ecm(that is what it looks like an ecm). Does anyone have or know where I can get a wiring schematic with labeled wires and colors of the wire for this machine. I have found them but none of them show the wires that go in the ecm. I would even be interested in buying an ecm(because the ecm female plug on the ecm looks quite worn) and the plug in with enough wire to hard wire it to my machine. Thank You for any help Chris
