I know there are a few post on this but I have question. Does anyone have a picture or videos of towing with a Prius C. Would tire size make a difference? Why do they make a custom tow hitch for a C but not a wire harness?
Tow hitches for a c are for bicycle racks, not for anything big enough to need lights. http://www.toyota.com/t3Portal/document/om/OM52B58U/pdf/sec_2-5.pdf (page 5 of the PDF, page 228 of the manual)
Here in the US, Toyota does not recommend that my Toyota Echo should pull a trailer, but the same exact Echo may pull a trailer in Australia and Canada. Same car. As for the Prius: Towing with a Prius: our experience | PriusChat I did a google search for "prius trailer", then clicked "images", and saw many Prii pulling trailers.
Check etrailer.com Probably the best source. I have bought a couple hitches and wiring sets from them and have been very satisfied.
Etrailer had the universal ones, were you have to slice the wires. I am looking for a T connecter flat 4 for towing. I know they have them for a PRIUS but I need one for a PRIUS C. Thanks.
