Hi all,
I installed a trailer hitch on my Renault Grand Scenic IV and I’m wondering where to connect the +12 wire. I found an empty spot in the fuse box which has +12V coming out of it, so I connected it there but now I’m not sure. The fuse for the trailer is is 15 amps and I’m concerned because I don’t know the gauge of the wire that feeds that slot (the back of the fuse box is not accessible enough so that I could figure out which wire is connected to that slot). I was wondering if such a connection is correct. I guess the question is if there is some standard of minimum wire gauge that feeds into the back of the fuse box?

BTW, the wiring is only for the lights of a small cargo trailer, not a travel trailer or anything…

Thanks!
