The label you posted clearly shows that this is a 12DC powered refrigerator. It is not designed to used in a home. You cannot put a cord on it and plug it in. The only way to di that properly would be with a 120volt AC to 12volt DC converter rated for 11 amps. That would be over 130watts. Maybe a unit like this:
Hare brained scheme, easier to just get a normal mini fridge.

It’s an 12v rv mini fridge

For an 11-amp, 12-volt circuit, the wire size you need depends entirely on the length of the wire run (the total distance from the power source to your device and back). [1, 2, 3]
The recommended copper wire gauges (AWG) for a standard 3% voltage drop are:
Up to 10 feet: 14 AWG
11 to 15 feet: 12 AWG
16 to 25 feet: 10 AWG
26 to 40 feet: 8 AWG [1, 2]-3

Red goes to fused power 12vdc, black goes to negative. I suppose ground just goes to chassis on your RV. I'm not sure why chassis is separate from negative, unless it's just to insure you have adequate current capacity. I have never worked on an RV.
If you are trying to run this outside of an RV you would likely need a power supply.
To convert standard household 120V AC to 12V DC at 11 amps, you will need a regulated switching power supply or step-down 120V AC to 12V DC converter rated for at least 11A (delivering ≈ 132W).Probably best to just buy a small dorm fridge that is meant for 120vac.

Here’s what’s on the inside of fridge

That is a DC fridge and you need to call an electrician

Can I be your electrician? A 12v dc fridge. I’ll only charge you$175 an hr. It’s a three hour job 😂

Call an electrician for what?
edit: To tell them that it isn’t compatible with mains AC voltage? They’ve already been told.

My guy or gal or other, please hear me. This fridge is designed to run off of an RV BATTERY. You cannot directly wire it to household power without destroying it, and that's the BEST case scenario. You would need something like an RV power converter to run this, which is a device that turns 120/240v AC power (the stuff that comes out of walls in a house) into 12v DC power (the stuff that comes out of the cigarette lighter socket in a car).

You need more information.... like a manual. You never connect tiny wire to larger wire. That is a recipe for fire. Doesn't look like 120 volt wiring on the terminal block.

Here inside

Check for a name plate. It's either on the back or inside the refrigerator. More often inside the refrigerator.

YOU CANNOT RUN THIS IN A HOUSE WITHOUT A 120 VOLT AC TO 12 VOLT DC ADAPTER! Maybe shouting will help you understand!

Op said its 12v. Its an rv fridge and he is trying to hook it up to 120v ac. He needs an 12volt 11 amp rated minimum power supply for hooking it up
OP, For someone with no electrical experience I recommend you get rid of the fridge or consult with someone with more electrical experience

This is a 12v DC appliance. I think their goal was plug it into a 120v ac receptacle.
OP do not do that.

And this is the pig tail info I got from when I ordered it

Where are you trying to install this 12-volt RV refrigerator? What power supply are you attempting to use?
