This idea I have has me stumped. Picture this: I have two Whelen 500 R/W split dummy modules tied into a flasher module. I want to be able to have the red and white flash on the flasher, along with having a separate switch that activates just the whites as a steady burn (not while the flasher is activated). So if I tie a hot from a switch and just tap the hot for the whites will it back feed and cause problems with the flasher? I don't know any other way to do it. TIA!
