Does anyone know if there is a plug n play wire harness for a 2003 Civic? I'd like to trailer my bike with my civic but can't find the correct wire harness to connect to the trailer for my year. I only see them for the 06-08 civic. Much help appreciated. Thanks.
you'll need a converter harness to go from 3-wire to 2-wire. that's what i did for my trailer. preferably buy a powered converter that gets power from the battery. otherwise, you'll risk burning up your stock wires by trying to power the trailer if it has a bunch of lights. 2 tail lights and 4 or less marker lights and you should be fine with an unpowered converter. it all depends on the type of bulbs and the total wattage draw. but no, there are no PNP t-harnesses commercially available for 7th gens.
