mohok1,
I had the same problem. Here is the advice I got and it worked. In the back wall of the RV there should be a terminal block with green wires and a terminal block with white wires. Green is positive(+) and white is negative (-). Hook up to these with the camera wires and don't use the pigtail. It worked for me.
I'm not sure. I have a guy installing it for me. Still doing research. Have reached out to jayco. Usually get a response via email within 48 hrs. Thanks for your reply
