S10 wiper motor = selecta speed???

[esenior]

bump - can anyone help me read the switch diagram... I see a 7 position switch with different resistance values.... not sure what the PULSE switch is... help?

Pulse signifies the intermittent settings, the switch in the middle would say the same thing, but the resistors are in the way.

The middle and far right switch are 2 poles of the same switch (denoted by the dashed line). Not sure, but if I had to guess, they used a second pole to completely isolate the PPL wire unless the wiper is on High.

You could use a single pole rotary, but would need to do something like run the High value to a DPDT relay that provided 12v to the PPL wire and 12v through a 680k resistor to the BRN wire.

Hope this helps! ---Eric
