Hi, I've been trying to install a WIFI thermostat using a C wire conversion kit I purchased recently. The installation instructions review the install steps at the thermostat which are pretty straightforward. When I get to the air handler piece I am stuck. To begin with, the installation videos and most documentation refer to a control board, I can't seem to find this on my unit. Second the one area I found which looks to have the wires connected does not have a "C" option. I am looking for the controller in the wrong place? Is this conversion kit not compatible for my AC?

This is the conversion kit I purchased:

This is the panel I found in the air handler which does not have a C option:
