apparently I cut into the side of my car, and I am suppoed to have cut down under the battery tray, should I cut the hole where it should be, or does it not matter?

if you want to see what I mean

 

i think you should leave it if everything has been functioning properly and you haven't had any issues yet....

its not going to look to good with that hole there...BUT if there is a functionality problem then yes reinstall it...

 

Chris is right
