I've been having troubles with my boat trailer lights. I tried all new grounds but no luck. I also switched to leds on the trailer. That helped somewhat but still blinkers only flicker while braking with headlights on. I'm reading that I might need a "heavy-duty" signal flasher but I can't seem to find one. Anybody know a source or model number? I think its a 5 pin.

 

You using a factory style wiring kit for hook up ?

 

No. It's got a curt converter on it(independent/common), but not the cool kind that has it's own power wire straight to the battery.
