Product review (4 stars): Perform a careful inspection.
I ordered this harness along with the rotor position sensor as a precaution. I installed only the sensor as I ordered the wrong harness. I required the 6877ER1016F instead of the B. The sensor however did not fix my concern. Upon close inspection of the motor harness I found a break in one of the wires. It is wrapped in a white tape and easy to see through, but I recommend removing the tape and inspecting it very carefully visually, and if possible do a continuity check on each wire with an ohm meter. I wanted to replace it but I mistakenly ordered the wrong one. I ended up repairing it by using proper crimp connectors and heat shrink tubing, and adding 4 or 5 inches of extra length. I suspect that this is a common problem with this type of machine as the motor is mounted directly on the drum, and the drum has a lot of movement and bouncing in it during operation. This is causing a lot of movement in the harness which results in work hardening of the wires which causes them to break. These parts are fairly cheap at about only $ 30 for both
