Thank you for providing that picture. In order to install the # SSR54FR on your Dometic AC you will start by removing the white wire coming from the compressor to the run capacitor and connect it to the blue wire on the SoftStartRV. Next, take the black wire from the SoftStartRV and connect it where the white wire was on the run capacitor.

The yellow SoftStartRV wire will connect to the red wire at the run capacitor that goes to the compressor. If there is a 2nd red wire going to the start capacitor, it must be removed and taped up at the run capacitor end. Remove the compressor cap and disconnect the blue wire then connect it to the red wire from SoftStartRV.

Connect the brown SoftStartRV wire on the terminal the blue compressor wire was on. Route the brown wire toward the white compressor wire and replace the compressor cap. Once this is done, secure all the wires in place and test your unit.

I also attached the wiring diagram and instructions from SoftStartRV below for your reference.
