We bought a 1995 mobile home lake house. The thermostat has a blue wire to RH and two yellow wires to Y. When I went to install the C adapter on the unit, there isn’t a panel with screws. I start the thermostat wires are connected with wire nuts. How do I install the adapter?

Try to identify the different wires coming back from the thermostat.
Connect the wires going to the thermostat to the adapter as shown and join the wires from the main unit to the adapter using wire nuts.
