Made in house wiring harness to adapt a car normally equipped with a CWA50 ( or bmw pump) to a CWA100-2 or CWA100-3 waterpump( specify in the drop down then add to cart). Waterpump harnesses will come with unpinned stock side connector . If you want larger wire gauge to run a relay for CWA150 ( I have found this is unnecessary) please send a message .
Will come un pinned to be universal . If you need a wiring diagram shoot an email with make and model then one can be provided.
