hey Ben, here is an idea of what Talev is talking about, albeit this is for a Gen4 but it's basically the same principals.


Take a look at
viewtopic.php?f=12&t=9366 for the text and so on, can't be bothered cutting it all in here.
That link is for a HID fog lamp install so basically none of that you need to know, but just get the general idea of lifting up the car (use jack stands please don't do what I did) and then basically remove/unfasten and bend down the plastic undercover, twist out fog globe, replace fog globe.
It's pretty simple, just looks hard.
Good luck
