Reddit reviews uxcell Car Charger Power Female Cigarette Lighter Socket Plug Adapter with 26cm Cable

using something like this:

http://www.amazon.com/Shipping-CIRCUIT-BLADE-PROFILE-FUSETAP/dp/B00K17A2E6

Allows you to tap into an existing fuse slot fairly easily, its pretty much unplug a fuse, plug it and two fuses in.. then you can wire to the existing wire and a metal to the frame point under the dash.

I have done this with my car since my cigarette lighters are always on.

I used it to wire one of these in: http://www.amazon.com/uxcell%C2%AE-Charger-Cigarette-Lighter-Female/dp/B00EZJBELQ

And I just plugged my cam into that.

Well, I have a splitter on that now and my cam and gps are on it.. but same thing..

Cigartte lighter socket + quality car phone charger + Add-a-circuit kit (check your fuse type) + some quality tape + Right-angle USB charging cable

You wire the red wire on the cigarette adapter to an add-a-ciruit (i.e. with a crimp tool). The black wire goes to ground (i.e. tucked under some bolt someplace, or a ring terminal ). You put the charger in the now-attached cigarette adapter in the fuse area under your driver's side dash. Then you need to route an appropriate USB cable (i.e. with one with a right-angle head or right-angle adapter on the dash cam side) to the under dash area (usually by tucking it under the headliner over the windshield, and then by popping the A-pillar cover off and the side panel of the dashboard, and feeding the cable through). Once you have all the wires under the dash, you just need to hook them up, test them, and then tape them together so they can't come loose.

The advantage of going this route is that you 'own' all the pieces. If any part of the formula isn't working out, you can change just that part. You also get a spare USB-C charging port for free since that adapter has both A and C.

You need either a in line wired USB or wire a cigarette lighter receptacle in and use your existing adapter. You can't just wire the USB cable in directly. USB is 5v.

I have a cig lighter wired in under the dash and one of those 3 output USB adapters for dashcam and some other stuff.

In my Mk6, I tapped into the cigarette lighter line and added another cigarette outlet inside of my center console. Then ran the provided cigarette lighter power supply line down the A pillar, through the fuse box, in the trim behind the wheel, into the console. That meant I didn't have to butcher the included power supply to wire it in, and I didn't have to find a fuse position that would work.

I stole the idea from the DoubleApex USB Charger install - I basically just did it a second time, but instead of tapping in their lighter/USB power supply, tappen in an outlet I bought. Here's their instructions(PDF) if you want to get an idea. May not be best for your situation, but it's an option.

Seems like the hardwiring kit in /u/nonvideas post is out of stock. You can use these two things instead:

This is what I used. There's a panel under the fuel lid/hood release latches that uncovers a small fuse panel. First, unscrew the big bolt you see (you may have to pry the bigger plastic cover slightly) using a 13mm socket. Tighten the bolt so that the black ground cable from the cigarette lighter thing is secure. Then, insert the red power cable into the red wire connector from the fuse tap and crimp the wire. Now you're ready to tap your fuse box. Take out the fuse you want to tap, insert it into the fuse tap, then insert the fusetap fuse into that same socket. Now you're tapped into the battery power and only the ignition will power the cigarette lighter.

About the least expensive way you can wire this up to your fuse box is to buy a 'add-a-fuse' and a DIY lighter socket, together these will cost you $10.

and here is a video showing how to do it:

You can buy these parts locally at any automotive parts type store, NAPA for example.

It's really, really easy to add your own ambient lighting to the Focus (or any car really). Most LED strips are already 12v. They'd need an adapter from house wall power but in a car (the vast majority of them anyway) the 12V circuits are already there! If you're concerned about your own electrical knowledge they make kits too; they're pretty inexpensive and you could splice open that cigarette adapter line to wire it in directly or get something like this. Personally I'd buy my own strips, controllers, and hard wire it though (make sure you confirm controller works with your strip). Since you're in the footwell I'd also recommend weatherproof but it's not super necessary since it won't be directly exposed.

You could tap in to an accessory line/fuse to have them always on or get fancy and wire them in to the dash lighting for when the headlights are on so that they only come on at night. I just used these fuse taps the other day for a dash cam and radar detector install; make sure you have the right fuses for your install though. I had to pickup some lower amperage ones to properly protect my lower amperage gear.

Some LED strip lighting is easy to adhere or screw down depending on your preference and you can even get RGB and an IR/RF/bluetooth controller to customize.

Anyway, the whole thing should take nothing more than an hour or two and less than $100 in parts.

That one is a 12v in but it's directly connected to an AC adaptor for a house, so I wouldn't touch it as you'd void any warranty cutting the wires. You can get something like this and wire it up with this, and your cigarette lighter should have enough amperage to power it unless it's not accessory in which case a relay can be used. Depends how technical you want to get with it.

Sounds like you're looking for a terminal block. You'll need a step down converter to take the 12v battery juice down to whatever your pi and cell phones require. You could also just wire a female car charger adapter and then use a car charger to properly do the voltage step down for charging cell phones and tablets. Raspberry Pi's require 5v and seem to work fine at USB 2.0's standard of .5 amps, but I'm pretty sure they'll work at the 2-3 amps most high end chargers utilize, but that all depends on what kinds of peripherals you'll be running.

What I did instead was buy a female cigarette lighter end (similar to below) and wire that into the power source. This way I didn't have to cut the dashcam power cord, and could move it to another car in the future.

I did a semi-hardwire install on my 2008 Civic. It is very simple.
 

Do you have any technical, hands-on skills?
 

Buy 1 of each. You can buy in AutoZone too.

Find a switched source (or constant if you have a camera that triggers when you are parked) using your multimeter, tap into it and route the wires. Should take 1-3 hours depending on your skills. DO NOT use the ScotchLok Taps.
