Is there a way to add a trim switch to the throttle lever on a control box that doesn't have a trim switch? I'm getting real close to installing the retrofit trim on my 72 100 HP Johnson and I need to install a trim switch. I would prefer to put it on the throttle handle but the installation needs to look good. The 72 control box is kinda unique so I don't think its as simple as switching throttle levers.<br />TIA<br /><br />Russ In Texas
