hey folks working on wiring up my rumbler to my whelen 295sda1 dual tone and I can't seem to get it to work. I will not be running a timer as I will only be running it for a few seconds at intersections. I have looked at the wiring diagrams and it appears that my version ( no internal timer) is powered by the red 12v+ wire. Is that also the trigger wire? Also how do I hook it up to the siren speaker outputs being that each speaker has its own + and -? Any help would be greatly appreciated
