Windshield washer pump motor wiring

[1Bad454]

Does anybody know where the green and yellow wires go?

[72 Monte Carlo]

One of the wires should be 12V positive, and the other 12V negative, and the pump completes the circuit. 

Attached is a picture of a 70 Chevelle wiper motor and washer pump.

The sad part about buying "off the shelf, generic" parts is that you don't always get a complete item.

Another downside is wires aren't usually colour coded to original.  

Those two wires should be fitted into a plug/block that attaches to the three point block that comes from the switch and feeds the two speed motor and pump. 

I've included a '70 diagram that might help...... But I think, (if you don't have a diagram) that you'll have to test which wire operates which function.... 

ie. does the green wire run the blade motor, or the pump motor ?? 

Good luck.

Man, I instantly get a headache looking at schematics (?) like this.  No thanks… I’ll write another check …

I agree. Might as well be speaking to me in Chinese ( no tariffs).
