Hey Charlie,
I'm wired for sound, uh, I mean a trailer.
The tailight convertor is needed to take the seperate turnsignals and brakelight into the combined brakelight/turnsignal that is on most trailers. Wally world, auto parts places usually have them for 12-20 bucks.
I tapped into the bike harness between the tool tray and seat latch. Easy peasy, most convertors are even labeled as to what goes where.
Ping me direct if you need assistance.
