I am considering buying a small trailer to tow with my 2003 CR-V. Web info says I will need a Tail Light Converter because the CR-V has (amber) turn signals that are separate from the brake lights. The Honda (optional) Trailer Light Harness plugs into a connector behind the left panel in the cargo area and extends a pigtail out under the bumper with a connector for the trailer. The Honda Trailer Light Harness has a built-in 'converter'. Can anyone tell me what it does? Is it a Tail Light Converter? Can you point me to a website where I can see a wiring diagram of the harness? Thanks for help Carl
