First, welcome to IRV2.com.
Assuming your dolly has lights, most folks just use those lights (when I had a dolly, I checked with my SPD and they said as long as the tow dolly had running lights, stop and turn signals, it was not required to also wire up the car on the dolly).
Now if you want to also wire the Honda to make your lights more visible, you can do that. You will need to run 4 wires (green, yellow, brown, white) from the front of the car to the rear tail light assemblies. At that point, you can either use diodes and wire directly to the existing lights (my preferred method), or use an 'add-a-bulb' system like those sold by Blue Ox and on etrailer.com.
The wires, of course, will need to be connected to your coach using trailer type plug/s. Assuming you also have to have the lights on the dolly working and that will be connected to your coach, you can splice into that for the car.
There are some portable wireless towing lights you can get but I am not familiar with those.
