I have a hot water pressure washer with the waterless steam clean so you dont get any puddles anywhere laying around and THEN I always blow it off with an air gun cause like its been said the connectors for all the sensors don't like the wet. So yeah that prolly was your problem with the wet sensor. Oh and yes it's tied in with the abs module, driver side with the metal lines coming from the top and the black computer part on the side with the huge plug.
