Cosmo, I do not know if this matters, but it is my understanding that you need to use a Trucklite Flasher with the SignalStat 900. They have different numbers than the ones you get at the local FLAPS.
The 263 Flasher is for regular bulbs. I can't find the proper number on Trucklite.com for the LED version but I didn't look super hard. Hope this helps.
The back of the headlight switch nearest the firewall has 3 terminals. All of them are connected together. THAT is your unswitched power where the turn signals should go. That way your emergency flasher works without ignition.
