On my Bounder its on the ceiling, right side forward compartment.
I have the out of production power gear elec system....laughingly now supported by Lippert.
I've put 12v to ea jack and they work fine up & down. After many shop visits and troubleshooting Lippert's recommended solution is to replace 2 of the 4 jacks ($2400). Even though the existing jacks test good and go & down with 12v applied directly....they couldn't explain why new jacks would fix the problem!
So I am going to the wiring diagram, install 4 three-way switches and by pass all the controller wiring.
