Hi I'm trying to replace the circuit board on a
masterbuilt I got used. Previous owner has pulled out the circuit board as it had failed (below). Simple enough but I'm not finding pics of the wiring so I can put it back together correctly. Anyone willing to share a picture of theirs so I can see the color coding of wires. Thanks!

Hi there and welcome!
I cant tell you exactly how to wire it if you can find a replacement board but
chopsaw
's pic below basically shows you where wires should likely go.
Circling back, I have a sneaky suspicion you won't find a replacement circuit board if you haven't already found one and gotten a confirmation that it is on its way or it's already in your hands.
If that is the case then your only option is to do a simple rewire of the MES and use a PID controller to control your MES. This is far superior to anything a replacement circuit board could do or any brand new MES unit could do for controlling an MES smoker.
The simple rewire makes it so the MES plug feeds power to the heating element while still keeping the safety limit switch in the mix. There is no control so the heating element will simply just heat up until the safety limit switch is triggered.
With this rewire you plug the MES into a PID Controller and drop the temp probe from the controller down the MES vent and clip to the bottom-center of the lowest smoker rack.
The controller will then take power from your wall outlet and feed it to the MES causing it to heat up until it hits and holds to the set temp you entered into the PID controller. Easy, peasy!
This makes your MES perform like $1,000+ electric smokers out there for a fraction of the cost!!!! It's like turning a golf cart into a Ferrari :D
I hope this info helps :D
Don't know what model you're working with , but this is a Gen 1 MES 30 .
I believe the solid wires ( white / black ) are line voltage .
