Directions for installing towing package on Saturn Vue

We lost our 2003 Saturn to hurricane Wilma last year. I removed the
towing package from it (minus the two bolts in fender tube). We have
since bought a 2006 Vue and I want to install the package on it. Of
course I threw away the directions long ago. I can figure out the tow
bar part but would benefit from having the electrical directions again.
Also I need to purchase the two carriage bolts that go into the fender
tube. Anyone have copies of install sheets and/or size of bolts I
need? Thanks for your help.
