I know this is an older post but I am in the process of doing the exact same swap as you did. Can you give me some information on how you dealt with the wiring issue or even pictures hahaha. RV and old Atwood has 4 wires connect and the suburban only comes with 3 wires. No clue how to solve the issue. Seems you may have figured it out?
Hi DonalMW I got the same problem I was looking on your post there anyway you can send me a picture wish wire color goes with the Suburban SW6del please
