In case “someone” helpfully discarded the factory wiring harness plug and then replaced your Chevy wiper control switch with another that doesn’t in anyway resemble the correct part, here are the 1968-1972 terminal wiring assignments for:
|Beginning Year: 1968|
|Ending Year: 1972|
The Brand is: American Autowire and the Manufacturer’s Part Number is 01993432
Of the two parallel terminals, the one located to the outside is for the Black wire, the other is for the Dark Blue wire. The third terminal which is offset (not parallel) is for the Light Blue wire.
You are welcome.
