I have this truck plug and had what I thought was the correct male half. I guess I was wrong.

 

What type do I need?

 

(Sorry, I don't know why it shows them sideways. They are correct on my computer.)

I'm thinking that what's in your hand is correct for the trailer side and is the female. There is another piece that goes between the plug in the top pic and the piece in your hand. Is that a GM?

Ford, but the guy did a lot of his own work and he did it poorly. 

 

So what exactly am I missing?

It's gonna look something like this.  

   

I'm thinking the plug you have will plug into the back. 

This might give you a better idea of what parts you have and which you need.

That looks like what I need. Is that part sold as a male half? Because that looks like the right end but in a female form.

The plug you're holding in the first post will go into the part on the truck I took a pic of. 

The plug on your truck looks to be part of the wiring harness that plugs into the back of the RV plug (what I took at pic of) then the trailer plug goes into the end you can see in the pic.  I'm sorry I'm not great at explaining things so I'm probably adding confusion

So so you're saying I have the right part and it should work?

 

 

Because it looks different than your pic.

No not at all. You are missing the rv plug for the truck. That's what I took a pic of. The plug that you took a pic of on the truck would go to the truck side of the rv plug. The other pic you took should be from the trailer and would plug into the other side of the rv plug. 

The plug is on the wiring from the boat trailer, the receptacle is mounted onto the tow vehicle.

There is a adapter available that your 4 wire flat trailer plug will plug into to adapt the flat 4 wire plug to a round universal plug that mates to your tow vehicle round receptacle. Plugs have external polarizing key (raised boss) receptacle will have a mating key way ( recessed notch) to align the plug to the reception contacts properly.

RV shops carry what you need. Your current plug and receptacle don't appear to be mates and are severely corroded and need to be replaced.
