I usually add a separate fuse block inside the car so I can install additional 12v outlets and accessories. Is there an easy way to get a wire from the battery through the firewall in a 2015 Fit?

 

I just used one of these and a Marinco 12V ACC socket in my EG.



Put it in the original fuse for the lighter and add a fuse of equal value for the new socket. Bada bing, bada boom DONE.

 

Look to where the A/C hose go into the cabin. Tape the wire you want to use to a straightened coat hanger. Carefully push the hanger along the hose into the cabin go inside or have someone inside pull the hanger until the wire is inside.

 

Clever.

 

Do you have a link for that? Is it for the small size fuses?

Got it!

 

Just go to your local auto parts store and pluck the one you want off the shelf.

 

I found a spot above the passenger's feet and ran a wire through there from the battery. A chopstick poked through the grommet, with a wire taped to it. That went to a fuse block and two 12v outlets. I decided to put a switch in one of the blanks on the left to turn the fuse block on and off, just for safety. I found these on Amazon, made by Laser Blue.
