I just purchased a DF70 and am hooking it up myself. It's hung, and steering is done. My questions stem around the Tach and the throttle. I don't have the instructions to install them, so what do I do? The tach seems easy on the engine end, but on the Tachometer, so are a ton of connections to which I don't think I need all of them, I'm not sure. Thoughts/help? Yes, I know I should get a manual, but I don't have time right now...
