Can anyone come up with a plan for a 5 wire to 4 wire trailer converter. My new trailer has US type lights and my car has, well you know, five. I know I can buy one of these things for 30 bucks but I thought it would be nice to build it for 5 bucks. I'am sure I am not the only 300D owner with this problem.
