Turn signal crap again

Part number 2947503 is the 8 wire switch, with hazard, without tilt or corner lamps. Correct for a lot of models. When you find this one NOS, it will be very expensive.
Part number 2947536 is the 11 wire switch. Pretty much the same switch as 503 except it is correct for the few models with corner lamps. Since those vehicles are fewer and far between, this switch NOS is more available and lower priced. I cannot testify that the 2 switches would interchange. Maybe @slantsixdan would know. 3 extra wires that do not connect to the cars harness to save a hundred or more deserves some investigation? Good luck
