I have a 2004 f150 fx4 that had a Hopkins 7pin/4 way trailer plug already on it. I have to replace the plug assembly and the wiring harness that plugs into the 7pin/4way. I have been googling and even reached out to Hopkins with no response. I believe the Hopkins plug is the 40955 but I'm not for sure. Can anyone help me thanks in advance

 

Any 7 pin/4 pin setup will work. If it says it'll work on our model year F-150, then that's what you use.
