Just installed sohn adapter kit. All good except original washer resovour had 3 connections. Washer fluid to window, low washer fluid connection, and a mistery pump sending washer fluid to who knows where. The replacement resovour had only one port used to send washer fluid to thw window. The low water switch was defeated by hanging upside down. Does anyone know what the mistery pump is used for??????

 

Likely headlight washers.. Cdn cars have them as well as some other markets

 

Thanks
