A vert might be a bit different, but check out the link above, the "Search" feature to the upper-right and the attached. I'd start in the trunk. There's also a fuse involved. If you'd like to turn the unit off, cut power to it, check out the fuse references in the Owner's Manual. There's a double fuse in the internal, cabin fuse panel that can simply be removed, while leaving cabling and modules in-tact.
It should be behind a panel found in the trunk, drivers side. So, I guess the unit is in the drivers side rear upper fender area, behind the trunk panel.
