If you don't feel like wiring, you can get relays that are prewired. Basically the prewpi hooks up to those via a control wire and all of the electrical wiring is inside. You would need two if you are going hot and cold and I think you can skip the relays.

It would be better to tackle the wiring of the compression/thermostat. Even if you don't know much about wiring, it would be a good idea to physically see how the compressor is currently wired up in your refrigerator. Take lots of pictures before you cut anything as you discover wiring paths, from HOT to NEUTRAL to GROUND. You basically want to bypass your current thermostat and replace it with the cooling side / solid state relay of the BrewPi. I used paint can light bulb heaters in my BrewPi build to heat the chamber. This was connected to the heating side / solid state relay of the BrewPi. :) Cheers!

Here's what happened the last time I tried to tackle any wiring - my wife and I were still living in Astoria, Queens.  I wanted to install a new ceiling fan / lamp in the bedroom we were renting fro, popped the old light off and saw there were at least 9 different wires in the housing.  After guessing on what to do I wired it up, turned on the switch and fried our building!  Luckily later that evening the giant underground transformer on our block blew up and caught on fire, so I blamed it on that  :D

I will take a stab at this and taking photos before I dig in is a killer suggestion, didn't think of that before.

Thanks!

1. Anyone know where to get custom decals (for the top of the door) for a GDM-12 fridge like this?: http://www.brewpi.com/brewpi-feature-and-review-on-aha-pimp-my-system-and-in-linux-voice/ If you just remove the existing Pepsi/ True decals you're staring at a fluorescent / LED (depending upon age) light, which isn't nice either. 

I REALLY want to remove the Pepsi logo and replace it with something custom, but I can't get the Ones and Zeros guy to respond to where he got his...


2. Anyone know where you can get 3rd party after market casters for these True GDM12s? -The official casters for the fridge are like $280 from the manufacturer which is a level of crazy I never thought I'd see....


Thanks,
Adam

I am the Ones & Zeros guy. Sorry for the late response.

1) The logo banner is a decal, the same van wrap material that is put on cars. I ordered the decals from here:

http://www.thesigncenterusa.com/


2) These are the casters you should get. Significantly cheaper. :D

You want backlit material. Near any sign shop should be able to produce one for you.

So awesome!  Thanks, Chris.  I've been stalking you around the interwebs to get this information so apologies in advance: you're going to have a message from me on pretty much every email, online forum, and FB page you have.  ;-) 

-That's what you get when you build such an awesome setup: creepy internet stalkers!

"Backlit material" -That's what I ask the sign shop for?  -And then just give them my graphics and dimensions?

Yep. A FedEx Office, fast signs or local sign shop should be able to assist. Save your self some dough and set the files up yourself if you can. Illustrator would be my first pick. File manipulation can run as mush per hour as a mechanic.

Haha! (To your response about internet stalkers) Thanks for the compliment! If you call the sign center (from the link I provided), ask for Dave and tell him you want the same van wrap material that was used on the Ones & Zeros Brewing order. Hopefully he will remember. He's a nice guy anyhow and has helped me with decals / signs on other projects too. Good luck on your build! Post pics when it's done and friend me on Facebook. I'm the Chris Allen from Nashville, TN

Thanks again.

Regarding FB: Already did and you'll notice a message from me there. (Told you I was stalking you.)  ;-)

Can anyone educate me on what all these numbers and terms mean on the casters?

I get what "threaded stem" means.  "Black Polyolefin wheels" -easy enough.

But what is "Plain bore"?

What does the measurement "1/2-13x1" mean?

I'm assuming that 3" is the wheel diameter, and then 1 1/2" is the width of the wheel?

Why don't these things come with wheels with brakes? -It looks like you buy and assemble the brakes separately.

--I'm trying to understand all the important stats on the casters mostly because this ebay seller charges 5x too much for shipping and I have Amazon Prime; plus casters are just something I know basically nothing about and I'd like to learn.

When I look at the original True caster set for this fridge (model 830275), the originals are 2 1/2" wheels by 1 3/4" wide, with a stem that it says is 1/2" -13 by 1" tall.   I'm so confused at what the 13 means.

Ok I'm answering my own question, but UNC13 seems to be a standard for threads so you know that they'll work together.

I've found two options that I THINK will work on Amazon that are Prime eligible:
$8.93 a piece with 1/2" x 1" UNC13 threads- seems safest except I can't find an option with a brake and I need 2 with brakes...
http://www.amazon.com/Shepherd-Institutional-Diameter-Polyolefin-Threaded/dp/B009PFCLT4/ref=sr_1_1?ie=UTF8&qid=1415775465&sr=8-1&keywords=casters+2+1%2F2%22+stem+1%2F2%22+13+1%22

Here's one that's only 2" in diameter, the wheel is wider and it has a stem that's 1/2" x 1 1/2" Unc 13 and includes a brake for $6.65 a piece...
http://www.amazon.com/Shepherd-Diameter-Polyolefin-Threaded-Capacity/dp/B009PFC1R6/ref=sr_1_4?ie=UTF8&qid=1415775465&sr=8-4&keywords=casters+2+1%2F2%22+stem+1%2F2%22+13+1%22

The 2nd one is closer to what I want but possibly a bit risky with the 1 1/2" stem... Hmm...
