7 pin connector water issue

Question

I am wondering if anyone has seen this before and if I am doing something stupid. The 7 pin connector on the trailer has a dust cap and I keep it on but it seems to be causing more trouble than it is preventing. I think when it rains, water runs down the cord and pools inside the cap, trapping water and corroding the pins. I have used electrical contact cleaner a few times and tried coiling up the cable a few different ways but water seems to keep getting in. I am tempted to just keep the cap off so there is no water pooling under the cap but I am betting that will just cause different issues. Any thoughts on how to keep the water out.
Thanks

Have you thought about mounting the dust cap somewhere facing downward? Then when you snap the plug onto it water would drain away. I can't say that I have ever had this problem as I have a fiver and the cord fits into the back of the pinbox keeping it dry.

Forget the cap. Squeeze some dielectric grease into the plug and hang it facing down and forget about it.Maybe also "tuck" it up under something nearby - (frame, propane tanks, whatever.)

I tuck mine into the rear of the pin box.High and dry and out of the way until we move the FW.

We use one of these:It mounts on the tongue and the plug goes up inside it to keep it out of the weather.

I tuck mine under the propane tanks - they keep rain form hitting it. I would skip the plug cover.
