Its not painfully hard, when I was taking apart my part car I noticed after bending the fender to hell with my bare hands (Because I broke the camera on my phone taking the car apart) that the hood release is routed from a gromet in the interior thought the inside of the left (Drivers) side fender and on top of the front bumper.
So all you have to do is remove the lower lower fuse panel/vent/foot well light cover and then remove the fender and then just route the cable.
For the first time the FSM (Service Manual) Does'nt list how to replace this.
Luckily for you Nissan FAST (Dealership program that the Parts people use to order parts) does:

And lucky for you I am installing 94 Q tweeters in my 93 so I had to take off the piece that holds the hood release handle in place so I will take a picture of it and where the wire is routed though in the interior.
