Hey everyone,
I found several great USB outlet install guides on these forums, but I went a bit of a different route.
First, I purchased this switch:
Amazon.com: QC3.0+5V 3A Dual USB Power Socket, Quick Charge Car Charger USB Adapter for Smart Phone PDA iPad iPhone Android GPS Use for Toyota: Beauty
Second, I took an old wiring harness connector I had laying around, and pulled the pins out. They fit perfect into the extra plug that is used for the smokers kit (which I never purchased). So I soldered the ends of the switch I purchased to these old connector pins. Then covered the soldered welds with heat shrink. I also covered most of the pin for that they didn't touch.
Lastly, the hot (red) wire pin was inserted into the pink/green stripe slot and the ground (black) wire pin was inserted into the white/black stripe slot of the factory smokers kit connector.
Zip everything up, should work with ignition power.
Disclaimer: Try this at your own risk, I am not a professional. Use a voltmeter if you want to double check your wiring.
If you have any questions, I am happy to help.
Thanks!
