relay

I replaced the brake light with an LED with a 3x strobe function before going solid bright. With the bike off it works perfectly; with it on it just keeps violently blinking with the brake engaged. Any fix?

Hello everyone, I've just made the worthy investment of switching to LEDs. I've ordered the respective 3 pin flasher relay for LEDs. My question is, how do I properly wire the unit such that I maintain the self-cancelling feature? Thanks.
