I eliminated my crumbling Hall sensor plug today by just soldering the wires together and eliminating the plug.
The Hall sensor wires are NOT color coded to the harness wires. I had to spend some time digging out the resin in the plug figuring out the connections.
On the Hall sensor plug there are three wires:
1-Red
2-Green
3-Black
The harness wires are colored:
Light Tan - goes to the Red on Hall sensor
Brown - goes to the Green on Hall sensor
Shield wire - Goes to the Black on Hall sensor
It worked fine for me. In fact it feels a lot smoother. I changed my Mobile One oil & filter also ....she's purring like a kitten.
