Firewall opening for sunroof drain???!!!

[BobbySpeed]

My passenger/right side sunroof drain is filled with water. I’ve tried the Weedwhacker line twisting spinning with the Terrel etc. have gotten past depends into the connector but then hit a wall. I’d like to go from the firewall up to the top with the sunroof training starts but I can’t find out where it is in the firewall. It looks like it should be that nipple in the bottom photo, but there is no hole in it for the water to exit. I really need to find this and be done with it already. I tracked it from the bottom of the eight pill or two behind the fuse box but after that my fat hands can’t reach it to follow it anymore.

Ok, I started squeezing it like a teet on a cow and water broke through. Now anyone readiy this post  knows where it is.

If your not driving through rivers or the like and you want a long term solution, remove the plug permanently.

I removed the plug then made a setup with silicone tubing that attaches to an air gun and blow out all four corners every few months
