Alright, this is all I have for pics on the wire.
This is where I ran my two power runs from the front battery.
There is an opening where I ran them and there was existing loomed wire than i just zip tied the two runs to.
From there you just tuck the wire where you can, zip tie, secure it, whatever.
All the way to the back.
Then if you can see at the bottom right that little bit of carpet that is cut, thats where I cut into the metal and ran the wire.
I can't really get any more pictures from the trunk because these were taken when I was installing and the box isn't getting taken out.
I can get pics of the ran thats ran under the car if you want.
Let me know dude I'll help you the best I can.
