Karl,
In post 7 & 13, I describe how we would put the hazards in a separate switch and how the factory switch would work. This is how I think you want it.:
The red power on the beacon would go to a switch, from the switch you would run a wire up to the headlight switch. You would remove the purple wire from the connector one the back of the headlight switch and plug it in to the switch wire. That would give you worklights whenever you want.
Without doing anything else, you would have a factory switch that was:
off
hazards
hazards/headlights
headlights
I would think that would work well for you as there might be some time you would want to work without flashers. But, if you want flashers on whenever lights are on, you would have to run two wires with doides on them from the worklights and the headlights, to the flasher wire. Then you would always have flashers.
