Update: connected to trailer directional signals can be distinguished.W/45-1819 isolater.
I have gone through 3 of these and finally got one that worked or so I thought. It worked for a couple of weeks and now I don't have turn or stop lights on the bike had to remove this in order for the lights to work again. I don't know were I am going to get another trailer wire harness converter I know I will not buy another one of these.
Bought this with (45-1806) vertical, and (45-1819) isolated. Installed it all but the turn signals cause the trailer lights to blink together (left turn, both lights right turn, both lights). Brake lights and running lights are ok.
And we can't wait to show you how it's done!
