USB Wiring Help
 

Hey guys. Need some direction on my next project. I am installing the wiring for my bumper and windshield lights to the pillar. Since the Pillar Pod I purchased has 4 switch spots I thought I would hook up a USB connection made live by a switch. So:

2 switches are for lights,
1 switch is for the USB power
1 USB connections

I believe I am good on the wiring for the lights. My question is should I wire the USB using a relay the same as the lights or is there another route I should be going down? Different consideration on fusing? I appreciate any feedback on it. Just want to make sure I wire it right in the first place. I want to have the ability to throw a short cord to my gps or iPhone since I like them in that corner when using them. I don't always which is why I figured I would put it on a switch.

USB devices pull very little amperage (like 5 amps tops). So long as your switch is rated for above that you could wire it without a relay. If you're using OTRATTW switches, they are rated to 20 amps ( I don't go above 10 amps with them before moving to a relay). You will still need a fuse between the switch and the power source.

Thank you! That helps!
