I'm a little late with this thread, but this info is really helpful. So, what is this OEM part that I need to install the Prodigy? I know mfiver had the instructions about parts and all that, but that might as well been in Chinese, I didn't understand a thing in that. If I wanted to buy everything online, what should my order look like to install this brake contoller? I'm not very handy, should I get a pro to do this?
