Best place to run a wire through firewall from engine?

I'm about to install a front camera (will activate by hitting steering wheel button with custom programmed VIM) , and front camera will by mounted in the lower grille.

I need to find a way to run that wire from the lower front grille, to inside the car to connect to the Midcity VIM which is behind the in dash 6 disc changer.

Any advice here? Would prefer not to drill any new holes.

Here is wire that needs to come in:

Jason...I put my VIM under the steering wheel column area. Would be easier to get a wire to that area. Just a thought.

Through the fuse box under the hood drivers side, there is an rubber plugs will keep it weather proof. Also it's the easiest way to do and no drilling required

Looking good Jason. I see that you have the module running. You just need to connect up the camera now?

Ok, is this you mean? Remove the cover on the top right side of this pic? (looks like 2-3 allen screws holding it in place?) Then I'll see a place to run the RCA cable through?





Need to run the white connector through.

Ok, well, that was easy. After I popped the box off, I could see light shining in from inside the car. Was able to get the wire into the engine bay fuse box in 2 min!



Now the issue is getting the wire out of the engine bay fuse box... At the front of the box there is a blank square rubber grommet that pulls out! Guess just poke a hole in it and that's it?
