For the Black Tank, As Coachmen upfit the Royales, Mine are Orange on top, then Green, Yellow and Blue on the bottom. The second set of senders has
the Brown Wire on the top and all the other senders are hooked in together to form one long connection.
Hope this helps. Dont know about the grey tank as I didnt need to fuss with that one.
