Don't 66s have two speed wipers? That diagram only shows single speed.

Doc here, :pimp:

Don't remember WHEN they went one to two speed..But that is the right diagram for a line produced car in 66..

On / Off seems to be the choice of the day back then though...

He can tell by looking at his switch, If it is on, low/Hi then it's a 3 wire , 2 speed system.

Doc :pimp:

You are correct about the Chevelle having a one-speed wiper system. I assumed it was the same as my 66 442, which has two-speed, though the motor comes as either a 3 wire or 4 wire.
