Unfortunately I do not have exact information on your vehicle's requirements. With that said though we can get what you need. Lets start with the charge line kit. This is intended to keep a trickle charge going to your battery so it isn't drained during your travels. It will not hurt a vehicle that does not require it so with that said you can add one if you would like. I can't guarantee but doubt that it would be required. for this use the Roadmaster Battery Charge Line Kit for Towed Vehicles part # RM-156-25.

As for the diodes use the Roadmaster Hy-Power Diode part # RM-790 this provided the input needed from your coach and your Nissan out to the lights. You will use two diodes per side one each for the tail lights and one each for the turn and brake. In this case your vehicle's turn signals will use the normal bulb while you're driving it and the brake bulb when you are flat towing it.
