Imagine 3110BH and Winegard ConnecT 2.0 installation problems

[fox_alice]

Hello,

I am trying to install a Winegard ConnecT 2.0 Extender to our 2021 Grand Design Imagine 3110BH, but am running into difficulties getting the wiring sorted.
Every time I try to connect the power switch to the breaker, the circuit blows(I've lost around 10 so far), and I cannot seem to find a wiring diagram, or applicable video instructions anywhere to help.

Does anyone know where to look for this information, or do you know how yourself?

I don't want to damage anything—as I'm not an electrician.

Any help is appreciated,

Thanks.
