The CC heater is not hooked up (already disconnected by a tech before)

I did have a few techs come out to look at the unit (and could have messed up the wiring).

Do you have a diagram of how they are basically connected? I have three capacitors: run, start + relay, and fan. There is also what looks like a sequencer. I would like to double check the connections if possible. Thanks for your help!

if you are trying to run the heat pump in cold weather and don't have the cc heater in use, you could be slugging the compressor with liquid refrigerant. this would cause the compressor to not operate and the breaker to trip.

I just connected the CC heater. There is also a wire that leads to a refrigerant line near the compressor as a magnet clip on. Where does this connect to? (contactor?)

that is to be used inline with the cc heater, i believe, to turn the cc heater on as needed
