Sorry I was slammed all weekend and didnt have time to reply. I also didnt have time to take new pics so I will try to explain using the old pics for now.
Please keep in mind that I am not an electrician and you should always consult an electrician before hacking any wiring, also I am sure there is potentially a way to fry your freezer and or your temp controller.
So here is the legend for the photo:
#1- Hot going from relay to status light/compressor
#2- Hot wire coming from outlet to relay
#4- junction for hot wire to status light/compressor
#5- junction for common to status light/compressor
A=Wire bundle going to your freezer compressor
B=Incoming wire bundle from your electrical outlet
In the above photo, what you are trying to accomplish is replacing the manual temp controller (where wires 1,2 and 3 are connected) with your new electronic temp controller. The way this freezer is setup makes it look more complicated than it really is because connections 4 and 5 are just jumpers to activate the green status light.
So the easiest version of rewiring would be to have your temp controller getting its own power, and all you would have to do is connect wires 1 and 2 to the your electronic temp controller on the terminals that are controlled by the relay (terminals 10 and 11).
For this tutorials purposes we will connect wire #2 to terminal #10 and wire #1 to terminal #11.
Now slightly more complicated would be using the freezers wiring to supply power to the temp controller. Wires 1 and 2 will still be in the same location since they are still used for the relay, but now you have to add a jumper wire that goes from terminal #10 to terminal #7. (This jumper wire will supply power to the temp controller and still power the relay). Then all you need to do is connect terminal #8 to your common wire (the white ones labeled #5 in my pic) and you should be good to go!
