Interesting. Two front bumper?? ARB up front? We're otherwise set up the same. Two front, two dash, two rear truck, two rear bumper, two trailer.

Did the scout trip thing a couple of weeks ago with new Kaymar all wired up, stock flasher unit. No problems at all.

I'd done the rewiring on the trailer connector, Kaymar bumper lights, etc. and had no issues at all on the trip. I always saftey check the trailer lights before every trip and again if I unhook the trailer.

Curious - did you blow a fuse leading to wanting/needing the heavy duty flasher.
