Key Features & Benefits

This cap basically seals off one of the ports on your trailer brake control module. It prevents dirt, moisture, and anything else from getting inside where it doesn’t belong. It’s a pretty simple piece, really – just a protective cover. It fits onto the trailer brake control module itself, and that module is what lets you control the brakes on your trailer when you’re towing. So, this cap is part of that whole braking system – it keeps things sealed up tight. Think of it like a little lid protecting sensitive electronics.

Symptoms, Risks & Replacements

Well, if moisture or grime gets into that module, it can cause all sorts of headaches. You could get intermittent brake function, or even a complete failure. It acts like a shield, keeping the internals clean and dry. You’ll notice if this is missing pretty quickly—you might see corrosion around the port, or just feel air blowing where it shouldn’t. It’s a small part, but a missing or damaged one can create bigger issues down the road. You can find these easily enough – Fixparts Online usually stocks them, and they're pretty straightforward to replace. It's a good idea to have a spare on hand, honestly.
