If you are looking to save some money, order everything you need then have a shop install.
I ordered everything from
Trailer Hitches & Vehicle Accessories (800)298-8924
for my Edge and my daughters Edge. Then if you find it at a better price they will refund 110% of the difference plus everything is free shipping.
I ordered everything, (base plate, tow bar, Air Force One) shop did there own wiring.
