Firstly, welcome to CHR!! Been through Ozark on my way to N&N a while back - nice country! I used the EZ Wire kit, and it's pretty well marked and the instructions are fair to good. You didn't by chance hook your power wire for the RR turn signal to the tail light side instead of the brake/flasher side of the bulb, did you? That would put the pulsing signal from your flasher into the tail light circuit, which might cross into the headlights via the switch? Just a thought....
