2004 Canyon 5-cyl After market radio

[The Horror Lab]

I am looking to install A aftermarket JVC Double din radio in my canyon. I believe it does not use a accesory wire but the data wire so I will need to route the acc switched wire to the fuse box which is under the hood not one in cab. Is there any other way to do this under dash?  I seen somewhere that there is a switched acc wire under there but want to confirm if there is.
