Most people will be able to take a couple looks at the end results and be able to see what's been done, but I've tried to take a lot of pictures so that anyone could follow along exactly if they don't feel confident in figuring it out. modifications like this, are definitely at your own risk, and it's definitely your own fault if you somehow mess up your car trying to follow these instructions. I've had this idea for a while now, and finally made some progress on it. I have a Garmin and hate having the cord to charge it strung across the car, and hate having to remember to charge it as well. to fix this, I've added a power cord directly between a fuse box and the Garmin, with the wires tucked away. I've also added a USB hub inside of the storage compartment between the seats. I didn't want to cut into any of the actual adapters, so the only reel thing that I've cut into was a cheap pigtail cigarette lighter multiplug and the inside of the storage console. I'll try to describe the garmin power first and the USB hub in a separate post. things I used adapter that came with the garmin cheap cigarette lighter splitter multiplug add a circuit/ fuse tap wire to send to the ground electrical tape electrical eyelet/ ring terminal for the ground wire first step would be to disassemble the cheap cigarette multiplug after I had the female ends of the plug free, I attached the middle positive wire to the fuse tap wire.
