Windshield WASHER pump is the only electrical thing not working on my VG33 510 wagon

This is just about the last thing I need to get working. All the major electrical is complete and car runs fine - even out at Pacific Raceways for lapping with the Alfa club.

 

I bought a new motor as pictured and the wiring diagram I have shows two wires to it - Blue/Red and Black/Yellow.

 

I have no power to either wire with the ignition on acc. Wipers work but nothing to the pump. I need to get a couple of new connectors for the pump because the wires are so tiny and then plan to connect it. Red to Red/Black and the Blue to Black/Yellow.

 

Does that seem right? Thanks again to all the electric geniuses, you.ve gotten me through it all.

The Blue/Red has power any time the ignition or accessory position is on. The Black/Yellow goes to the wiper switch and is connected to ground in the 'wash' position to turn the pump on.

 

It may pump if wired backwards in reverse. I would test the pump to see which way makes the pump work best and wire it in accordingly.

A new pump is the best way to solve washer problems! Often the low cost to buy one is to buy a new WW assembly and throw away the tank.

Wired and working! Thanks all - just need to aim them. 😱
