I just bought a 930bt, but i do not have the rca connecter cables that plug into the back. Is this just needed to hook up the cammera, our would I need it to hook up my amp/sub aswell.... also, all the videos i have seen for the park brake bypass invole moving the yellow wire on that rca connector harness. If I do not have that harness am i still able to do the bypass ( with the green park brake cable) on its own??
thanks
