I'm trying to replace the wiper switch in my 66 F85. I recently picked up another switch that also was on a 66. I go to pull mine out and it has a totally different body and plug. Can anyone help me Id what switch goes to what and if anyone has a match to mine? Mine is the first 2 pics, the one I got is the last 2 pics

 

Square wiper motor vs round wiper motor. Single speed vs two speed wipers.

 

The wagon has a 2 speed wiper and a square motor. The other car I think had a round motor. I'm gonna go look at my 442 and see what it has. Since they were both 2 speed wiper cars, I didn't think it would be different.

 

There is a difference between a F-85 & Cutlass switch. You can change the wiring in the connector to make either switch work. The dash harness in my car is from a F-85 and my car is a Cutlass. All I did was change the wiring sequence to make it work.

 

the one you purchased is from a round wiper motor just like my two cars have - 66 442 and 66 cutlass conv; so believe the orig one for the f-85 is for the square motor.

 

Ok, to make things more weird, my 66 F85 Deluxe 442 has the round wiper motor, still trying to find the wiper switch to compare it. This is driving me nuts.
