Correct adapter?

I recently purchased a 1979 airstream. I'm not sure the model because it's parked out of state. I need to move it soon.

I'm trying to identify the name of the round black hook-up that allows my vehicle to activate the brake lights and turn-signals of the airstream. I failed to take a photo. I believe the adapters called "seven blade". Am I correct that this is what it's called? Are there any variations that I need to be aware of?

My vehicle has a flat four pin.

I plan to buy the adapter at a local chain store like Pep Boys or AutoZone. Does anyone know if they carry the correct adapter?

You're some examples of what I'm asking about:

Correct adapter?

You will need the male plug that matches your TV.
Unless the trailer has been towed by a modern vehicle the chances are you will have to rewire the plug accordingly to match your TV.
The TV should have a brake controller as well.
Since you only have a 4 pin connector. You will not have brakes on your coach.
It takes a total of 6 wires to have what you need for towing.
Tail/marker lights
Brake/left turn signal
Brake/right turn signal
Charge line.
The Tacoma you have in your profile is not equipped for towing a coach of that size. The 4 wire plug tells me it does not have a tow package. Without a tow package there is no transmission cooler etc.
The hitch, if there is one may not be rated for the tongue weight. Even with an equalizer.

Are you going to use the trailer brakes?
The higher your expectations the fewer your options.

I had not planned on using the brakes. It's a one time tow.

I wouldn't tow an Airstream without brakes. Especially, from "out of state".

Inquiring minds want more details,

The tow vehicle you plan to use to recover the Airstream and how the T/V is equipped.

The size of the Airstream.

The condition of the tires and wheel bearings and brakes on the A/S.

Your in Oroville, any way you go to out of state requires going over mountains.

You will need brakes ! And a robust Tow vehicle if the A/S is over 2500 #.
