I want to put a mini refrigerator in my International truck.....I have an inverter

I run an 1500 in my truck. I use a Frigid aire refrigerator with a freezer and have no problem. Leave it running all the time. Low voltage warning is set at 12.3, and to this day I still haven't had it shut off the inverter.
The refrigerator was only 129 at Walmart. One of the best investments to date.

 

Bought mine at home depot.....got 2year warranty for $18....if fridge stops working...exchange at any home depot ...get free replacement...or full refund...for 2 years

 

Ooo it's a pure sine wave inverter. That should work really well, that's the best kind to have. It'll be big enough to handle a fridge.

 

I have a 2015 International lonestar that has a Cooper bussman control button pad in my sleeper. I just realized I don't have the inverter to it so I'm looking to buy one of these. The only problem is I don't know how to wire it up. Do any of you guys with a similar truck have any pics that could help me out to get this thing hooked up?
