I moved it all the way from under the car, till it reached the passenger floor. There I found a drain hole, which I was able to get the cable into.
This wiring was done to get the wireless receiver box next to a 12V output. I used the one next to the gear shift. Removed the panel there and split into it. Don't worry, you see nothing. Everything is hidden and thank god I have the remotes to use the cutout. IF they didn't have this feature I would've never thought of going on with it.
