Hi Bill
This is the one I have. I like it for a few reasons.
One the glass door.
Two it has a on & off switch for the light, so I leave the light in the on position.
That way when the fridge comes on the light comes on too & I can see that everything is working & how often the fridge cycles on & off.
It also has a manual temp control, which for this application I think is better. The digital ones seem to default to the highest setting when the fridge loses electricity.
For the wires I just put them thru the door on the hinge side. You can adjust the door so it closes a little tighter on that side so there isn't an air gap. I can put my hand right next to the wires & not feel any cool air escaping I was afraid to drill because it's hard to tell where the refrigerant lines & electric wires go. Also get yourself a small computer fan & a dimmer switch. I leave the fan on all the time on the lowest speed. I think it helps keep the air circulating. I also found a great website

They have a ton of videos on curing.
Hope this helps!!
