So recently my car has had the infamous leak where the passenger floorboard and ecu area gets soaked. After replacing all of the weatherstrip on the cowl and getting brand new grommets and drain plugs from the car, I've found the in the very upper corner above the blower motor box where the body curves for the fender the stuff they use for the seams just eventually gave out and started leaking water. I do not plan on getting rid of the car anytime soon, so I've gone through a whole can of Flex Seal spray and that absolutely has done the trick. Just have to apply a couple more coats and all is new and you could never tell. My issue is now that water is getting through a big hole where the ECU harness from on the inside frame of the car. I am not sure if there is supposed to be a grommet there or what but if it's possible can someone help me find the part number or a fix to fix the hole.
