So, I hate filling other people's threads with MY problems, but I am going to continue to do so here because I don't want to fry anything, or cause a fire. The other aspect of sharing my difficulties is that they may help others who are as inept as myself in trying to build their own thermoelectric drying/curing device. I considered DM'ing Hook Daddy, but then others wouldn't benefit from seeing how to approach the build from with shaky electrical, or fabrication skills.
So, with that out of the way, here is the issue I am facing now, and hope someone will be able to enlighten me on a solution.
In Hook Daddys initial description of how he stripped the dehumidifier of most of the electronics, which were unnecessary, he stated in post #3 of his thread:
I first opened the Inkbird and removed the humidity sensor connector from the circuit board. It is smaller than the sensor itself so you can drill a smaller hole in the fridge later. Here’s what it looks like inside the Inkbird with the connector on, then removed.
Connector removed.
Then I stripped all the useless stuff off the dehumidifier leaving just the unit itself. Here’s with the front of the case removed.
Here’s the rest removed.
There is a small circuit board you can leave if you want. I removed it just putting the humidifier and fan power together with the power wires from the small plug in transformer, of course positive to positive, negative to negative. If you don’t know about wiring get help or just leave it as is. I only remove the case and junk to save space. Oh I ditched the water collection bin as well, the water will drip from the fins of the dehumidifier into the channel in back of the fridge made for draining.
To the bolded: I understand connecting the power wires from the dehumidifier part, to the fan on it. My question though relates to wires from the "small plug-in transformer". I will include pictures of the other electronics so maybe someone can point out where the transformer is in the dehumidifier I am using in my build.
I am assuming that if I connect 110 ac power to the fan and dehu without the transformer, I will fry something as the purpose of the transformer is to step down and rectify the 110v ac to 12v dc? Am I right? If so, do I need to include the transformer? If so, how do I connect to it? I don't see the transformer in Hook Daddys build. I am confused. Here is the circuit board i removed, but still have:

" Wiring is the same Cut the Red and black wire from the Circuit board and wire directly to a 12v power supply. connect to a humidity controller ." So, I'm not sure how to connect to a 12v power supply is my question I guess.
Also, I'm kind of a hack when it comes to fabricating, or understanding how things work. But, I'm sure I'm not necessarily alone in that regard. Hope my questions help someone else too.
