Just purchased new pump motor assy PN ap4371966 (6-904608). This unit has a different wire harness than the old one. It still has four wires but they are all white and the wire harness on the machine is color coded. Also, there is an adaptor harness that contains all four wires. On the old harness only two of the wires go through the four pin connector. The other two are separate and have their own two connectors. The part came with new start relay and that seems to be correct. Do I have the right part? Is there a different adapter harness? Can i get a wire ID chart? Anny help would be appreciated.
