New Led Flashers, No Flashing

All I had to do was put new turn signals on my '97 T509 and I'd be out for a ride - but NOOOOO, we couldn't have that!
So here's the deal: This bike had been wrecked and didn't have any flashers when I bought it.
Installed the flashers and get nothing
Checked the fuse, checked the new LED relay, got 13 volts at the relay receptacle and 1.3 volts (variable) at the flashers.
Also these flashers are three wire and the system is two wire.
I hooked up the "ground" and "signal" wire and then I tied in the "running" wire, no difference.

Before I pull the tank to investigate further, is there something I'm missing?

 

Aha - yes, I'm trying to use the JL - Damn it, more screwing around with parts
Thanks Shamus!
