For those that might be interested it was hidden high up and close to the outside wall in the battery bay. I had to remove the fuse box from the wall so that I could open it and replace a blown 20A fuse. When I reinstalled it the bottom mounting hole became the top mounting hole and I drilled a new lower hole and mounted the fuse box at an angle to allow better visibility and access when replacing fuses.
First pic is the before and the second pic (rotated 90 degrees CCW) is the after.
