I thought I found a 7+4 connector at Tractor Supply Co. If you were closer, I would rip mine out and give to you. I hate those POS 7pin plugs. Don't stay connected for anything. All my trailers use 6-pin and they actually work. Unfortunately I haven't had time to wire the truck with a 6pin plug yet, so I have to use a POS adapter. Don't even get me started about adapters...
