Just a lot of stuff needs to come out, but not hard at all.
You need to pry up the scuff plate to free the kick panel (all driver side), 2 bolts to remove lower trim panel - one is obscured by the kick panel so you need it off - and free the hood release cable, another 2 bolts for the metal plate. When you are halfway through you'll see this:
(you don't need to remove the steering column cover like shown here)
You want the beige fuse box. Integration relay is clipped to its back. It's secured by one screw to the back. Unplug everything that gets in the way, undo the screw and free it.
Once you get to the integration relay, carefully pry off the clip and the relay from the fuse block. Plug everything back together and test the relay first. Once it's good put everything back together.
Good luck.
