I was hoping to get some help Identifying these 2 plugs I discovered today while under the back of my truck. They are on the driverside frame by the trailer hitch. I took a picture to post here so maybe somebody has used these or know what might plug into them????

Thanks in advance for your help.

 

I'd have to look under mine again, but I'm almost positive the 6 plug is to plug in the 7 way trailer plug that is in the bed on the driver's side near the tailgate if you order the factory gooseneck or 5th wheel setup - however I purchased the in bed plug at the Ford Parts dept and added it myself in the bed even though I didn't order the factory in bed hitches as I had a B&W Turnover Ball installed. I don't know what the 2 plug is.
