...if youre determined to do it yourself search astoria mercedes on youtube. a google search will probably turn up helpful tutorials. good luck.I have the option of using a PVC insulated wire - if that would work.
I decided not to check the potentiometer as this asks for dealing with the axle - I am doing only the harness as shown in the pics (soldering and heat shrink sleeve)
You can just remove the board.You'll just need to unsolder a couple of wires to allow clearance if I remember correctly. Also, you can actually unsolder the old wires from the pins that go in the connector end.New major challenge on the circuit board, as one of the thick wires is hardly accessible behind the board.
