I purchased my 3rd CX-9 this week. The newest being a 2015 GT with only 10,000 miles on it. I have added trailer hitch's to the previous ones a 2008 and a 2014. I used after market wiring harness's with no problem for the previous 2. Since this one is a GT model I understand their is a plug hidden under the storage area and you can connect a Mazda wiring harness 00008EN 13B directly to it. I have also heard you need to add a fuse somewhere near the glove box? Can anyone enlighten me on where the fuse is and what amperage it should be.
Thanks
