Going to try pictures this time. I have two switches. One is part number 3488781 which I was told is a 1972 only two speed wiper motor switch. I have another switch which is part number 3488764 which I think is a 3 speed wiper motor switch. OK, so I had to purchase a used dash harness as mine was toast. Everything electrically works fine but when I cam to plugging in my 2 speed switch, I realized that the donor harness came from a 3 speed wiper motor car, I believe. I just now received what was suppose to be a two speed harness plug to try and swap them out. Upon checking, again, my 2 speed switch will not even come close to plugging into the plug I was just sent? So I am posting pictures of the two switches and also the plug I was sent as a 2 speed plug, and also the 3 speed plug which is still wired into the donor harness I installed. HELP????
