Unfortunately I’m from from Europe, but I can provide you the schematics of the wiring so you can diy it. Good luck with your project nevertheless !

The instrument panel junction box has one free connector slot on non nav cars which you can use to get acc/rem etc. You can access it by removing the middle clock and ac, its right in the middle of it. If you need more help hmu.
