Universal 12v washer pump terminals

Just bought a replacement washer motor. No terminal indicators or wiring notes with it. Any one recognise it to know which is +ve and -ve? Thanks ...

 

Unlikely to matter which way round you connect it. If it’s wrong, swap the connections over.

 

Thanks, will suck it and see. Hopefully it will suck.

 

Should work fine.

 

If the polarity is wrong she'll run backwards

 

Dont forget to install it wet end down. Or when the pump shaft seal leaks the motor fills with water and rots.

 

All sorted thanks! Ground is the furthest away from the screw ...
