The LED flasher that I bought was garbage, I updated my previous post with that information. I've replaced it with a more expensive electronic flasher that shouldn't suffer from the terrible electro mechanical issues the one I first bought has.
The new LED Flasher (FL3-RED-K) is a three pin flasher but the GBS Zero's flasher socket will need to be re-pinned. The short story is that the GBS is pinned for ISO relays, FL3-RED-K relay that I purchased is pinned as a JSO relay. Research into that what you will but the following diagram should help on that.
Basically, looking at the back of the Relay Socket everything needs to rotate one tab clockwise.
