Made in the U.S.A. (at least what I got was), unlike the rest of their products which are made by slaves in china. These are decent covers to keep both the male and female connections clean. But you either need to remove them completely and put them in a clean place when connecting the trailer or you'll have to clean them out before recapping the connectors or they'll be rather useless. Thankfully the retention strap comes off and goes back on fairly easily so it's not difficult to completely remove them and put them in the glove box or some other clean place. I also recommend using an antioxidant joint compound on the connections to keep them from corroding. Electrical connections which are kept clean and free of corrosion are so much more reliable.
