The "junction box" is on the driver's side of the engine compartment up on the side. It is a bit tough to open up. You will think you are going to break it open and then it pops open!!

I do not have any experience fishing the cable from there to the lever. When I did mine it was from the junction to the actual hood releases.

Take a look to see where the cable goes through the firewall and then were it comes out in the interior. Should be pretty straight forward. Probably have to remove the hood release lever in the interior to attach the new cable.
