Ok, let's pretend that I'm a complete novice when it comes to wiring because, well, I'm a complete novice when it comes to wiring. If I wanted to add a 12 volt outlet like this:
To my van in order to power a 12v DC fridge like this:
Where does the negative wire go at the converter? If I'm correct I'll wire the positive to an empty circuit and add a fuse, but it's there sooner in the converter to hook the negative to? I know there's a negative block on the AC side but I don't see anything on the DC side. If it matters at all I've already replaced my stock converter with the 3 stage progressive Dynamics with the upgraded DC board. Thanks in advance for any assistance.

Re: Basic (?) 12v wiring question
Photos of your actual wiring/layout would help...
And someone may correct me, but your 12-volt system is probably wired so that the negative side of the circuit is the vehicle frame/chassis itself. So, you'd attach the negative side of the connection to any good solid metal connection in that case.
Same way most people connect the negative jumper-cable to a good frame/ground bite, instead of biting on the battery itself during a jump-start.

Yep, just hook the red to positive and the black to any convenient ground (metal part).Millennial Falcon wrote: ↑Tue Aug 27, 2019 9:47 amPhotos of your actual wiring/layout would help...

Make sure the cooler doesn't pull more current than that adapter is good for, though. I don't know the numbers on either; just wanting you to be safe. (In particular, is the red wire heavy enough for the current draw?)
