Hello Everyone,

I would like to make charging devices in the car a little bit more efficient. I would like to be able to charge things up front instead of having to run a long cable or cables to the back of the cabin, where the 12V outlet is.

I can tap the wires from the 12V outlet and run them under the center console pretty easily but then the question becomes what to do. I have a few options but would appreciate some input

1) Is it safe to do as far as draw? The most that I'd be charging at the same time would be a phone, a gopro, and a Garmin GPS unit.

2) Due to availability of items, I'm currently favoring having 2 12V outlets coming out of the front of the center console (right below the door lock switch). I would then be able to use one of those "12v car to USB" modules and call it a day. I like this idea over having anything in the dash, although USB ports coming out of the blank panel on the passenger side would be nice, albeit too much of a pain in the rear.

Thanks for your help!

As long as you use the appropriately sized wire you should be fine for tapping into the rear lighter plug. I am guessing you would only be pulling only an Amp or 2.

You could also tap the stereo power that's already under the dash. That's what I did to power my gauges and USB outlet/charger and radar detector. I haven't had a stereo in the car for many years so I'm not powering both however.

I think it's the purple/green wire in the harness. You could either cut into it (with a vampire clip) or get a new harness and plug it in. That would negate your stereo though...

There's a spare switched circuit in the fuse block under the dash. Lots of documentation here.

For power, I had good luck mounting a USB port in the small panel to the right of the steering wheel column down inside of the trinket tray in my old Elise. A friend of mine installed a power port in the front by buying one of the switch panels for cars with driving lights and mounted the power port in the new extra light switch opening.

This might be useful for wiring up the gopro and radar detector, since they'd be mounted up on the windshield and I could run the wires down through the a-pillar.

I have one. It's a Pioneer. But one USB port doesn't charge a phone, a gopro, a radar detector, and a stand alone GPS unit.
