Have run into some issues installing the C-wire adapter. First the wires going to the controller board on the air handler (hard to work in crawlspace over garage) are as follows
Wire color Terminal label
Which of these attach to the following terminals on the C-wire adapter
I assume Green goes to G, Red goes to R, and Yellow goes to Y , but does White go to W or is it White and Blue?
Do I wrap the ends of the unused wires with insulating tape and leave them in the air handler so I can reconnect them if I have problems with the Wyze thermostat and have to use my old one?
Finally the wires do not screw into the controller board but are inserted in a connector that is plugged into the board as shown in photo below. Does anyone know if those wires can be released from that type of connector so the wires from the C-wire connector can be inserted into it and then plugged in? If not, would you cut the connector off leaving some wire sticking out and then solder the wires from the C-wire adapter to them.
Any assistance appreciated.
