Wiper switch please help

Here are a few pics of my set-up. The switch I have is different to the one you have installed....note the gold three wire module at the seven o'clock position.

This switch came out of a '72 Demon with electric wash.

My Demon has a two speed motor (was foot pump)...now electric wash. All I did was install the new switch and add the far right hand side blue wire you can see into an empty slot on the OEM plug (this contact is 12V when switch pressed).

I then ran that additional 12V wire to the new wash motor.
