I too would like to see a photo of a complete wiring. This new ATS 503 is confusing. I called Parallax about the wiring for the ATS 503 and what he had to say didn't make sense after we got out there to actually do the job. If anyone has a completed wiring picture of this beast...please share. We are trying to get ready for Arizona by the 25th of Oct to fulfill my hubby's bucket list. Thank you.
