Haier wine fridge fermentation chamber

[KegGut]

This is a pretty simple mod thanks to fall-line's instructions. I just picked up a used Haier BC112G off CL and an Inkbird ITC-308 off Amazon. I took a picture of the electrical connector I used as a shunt to hot wire the compressor, it was a perfect fit.

I have this same model fridge. Looking at your first picture, you have a red 'shunt' that connects both white wire connections. It's not connected to anything else that I can see. Is this all you have to do in order to bypass the internal temp controller? Just shunt the white wires together and then everything runs as normal with an external temp controller?

I followed the lead of Fall-Line and used a piece of 16 gauge wire (black) to jump the connection. However, I noticed about a 10 degree fluctuation inside the chamber. I use an Inkbird ITC-308 set to a 1 degree +- and a small space heater plugged into the heating port. The temp seems to hold steady at the lower range of 50deg but when I set it at 62deg for a diacetyl rest the temp ranged from 58-66deg. It seemed to stick at 66deg more than going up and down. Did I miss something with the wiring?
