(Have a 911 for your time)

Alright Oppo, I need a bit of your help in figuring this out. If you have access to repair manuals/diagrams or that type of stuff it’d be great.

So my RSX sprung a leak, woke up to go for a drive and the entire passenger side floorboard was soaked. Now, searching on forums (which weren’t much help) leads me to believe it’s a sunroof drain plug.

Is there anyway to confirm that before I start pulling apart half the interior to check them out? We’ve got a chance of rain this weekend in my area and I’d like to take care of it before that.
