201s have that same sensor, I'm leaning toward wireing for two reasons

1. it is worn like no tomorrow, I already replaced a few wires and connections, but there is still many to replace.

2. it all started happening after I washed the car, so it's possible water is stuck somewhere on a wire causing a short which does this.

I plan to take apart all the thick plastic insulation and replace it with my own, and at the same time fix any suspicious looking wires.

Just gotta go to a junk yard strip a few more MBs of all their wires so I can color match then together
