I bought a new 7 pole RV plug for the trailer project. I wired it all up. The &^%$#! plug would not go into the trailer receptacle on my 01 truck. I don't have the packaging but think it came from WalMart or Harbor Freight. The noticeable thing about it is the silver (plated) contacts which extend beyond the cutouts in the plug body. I tried beveling edges, went over it with a digital caliper... every dimension is +.001 strong. I removed the round center pin just to try but still no go. After taking the wires out, I was able to force it into the socket... but I'm not going to use it. Before I went to the store, I looked in a box with my spare brake controller (took back off my half ton when I had to give it to my ex-w in the settlement... it was not bought with a trailer set up, she didn't get it with a trailer set up.) It shouldn't have been in that box but I found an almost new trailer plug... This used plug fit & I used it. It had all brass contacts & brass screws, everything. I have no clue what trailer I had it on... maybe my old stock trailer that I sold. I thought the plug went with it but maybe not. If I had to guess, I'd say the non-fitting plug is foreign made on metric machines. I wasted a lot of time on that plug so an very unhappy.
