7-pin receptacle on an F-150. When I plug the trailer in, the reverse light fuse will blow. If I remove the fuse, plug the trailer in, and reinsert the fuse, no problems. So it seems that it is something that is happening when the plug goes in. It happens with different trailers, so it must be on the truck side. Anybody have this happen before?
I've been just removing the fuse when hooking up, but that's obviously not the most convenient process.
