Just got a remanufactured wiper motor for our 67. It has 4 wires.. Red, Black, White & Blue. I'm guessing red/black = power/ground and the white/blue are for the 2 speeds low/high. Is this correct? Anyone tell me which is which (low/high) off hand?

I need to know which is which since I have an intermittent dial switch w/push button wiper squirter. New on/off lever on the Ididit steering column going to the intermittent dial switch then to an A/B toggle. 'A' will be for low which will stay as the default likely and 'B' will be for High. When the column lever is clicked ON the intermittent dial will provide 20 second delay to constant (at low speed) in 2 second selections. ie every 2,4,6..20 seconds or constantly on. If raining hard toggle from A to B and you get High speed.

I hope this is the correct thinking. The entire wiring bit is definitely going to be a learning process for me.

 

Looking at the FSM for a 66 I'm going to hazard a guess that the blue is the high speed and the white is the low speed. That would correspond to the view that indicates that one speed is across the commutator and 1/2 way across is 1/2 speed. Sorry, can't be any more definitive than this. jlg

 

On my '70 mustang two speed wiper motor the wiring is: white---low speed, blue---high speed, red---hot wire for parking the wiper blades and black---ground.

 

Ahh yes. I remember reading that now.. that red was Park. Thanks.
