It's crazy that everything still worked (other than the RH tank reading incorrectly). I plugged the connectors in correctly and everything works perfect now. Thanks everyone for all the help, especially Hatzie!

Thanks for posting back what you found. It helps people out that may be having the same or similar issue.
