Wiring Diode Dynamics SS3 Sport to factory switches

[JohnSadler]

I just purchased a set of Diode Dynamics SS3 Sport ditch lights for my TRD Off-road Hybrid. My truck has the factory switches. Has anyone installed these lights using the factory switches? Any tips?

Not these lights, but other lights. It's a simple deal using the provided pigtail. You will have three positive wires, and a ground. Aux1 is 15A, Aux2 is 10A, Aux3 is 5A. I believe the documentation that came with the pigtail will give you the wire colors for each (I don't remember off my head). What is the total load on the lights in Amps? Start there. Do not exceed the amps on the Aux circuit. If necessary, install a relay powered, and fused, off the battery.
