Honda BF 20 steering and throttle controls help needed

Hi again. I just finished installing my console and steering system on my 14'Lund.I have a rotary system and the cable is now sitting at the engine awaiting attachment. I do not have a tube running through my tilt section of my engine so I have to install a support bracket and external tube to attach it to the engine. I think with my limited experience i can eventually get it done. I would like to purchase a remote box to control my throttle for sure as I am withing reach to change from forward to reverse.I need help selecting the proper box.I have no idea if there is anything on the market to attach to a Honda BF 20.Only thing I have discovered so far is that I need a push type controller for the throttle.Any help will be greatly appreciated.
