No different than any other installation. You'll need to select a tow bar and base plates for the CRV. The hardest decision is selecting a braking system for the Honda.
So there are many brands to choose from for the above products or go with one that combines them all. Ready Brake (by Night Shift Auto) makes an all in one tow bar and brake system, reducing costs and adding simplicity. You'll still need to buy base plates to attach to the front of the CRV.
Just my personal opinion.....I like the Ready Brake for lighter cars, like your CRV, but not a fan of them for something as heavy as what I tow.
Lighting is fairly easy on the CRV. A company called Etrailer sells a kit that easily connects the taillight wires into one unit.
Lastly, the CRV has a battery smaller than some motorcycles, which can be problematic when towing. For about $100, you can buy a battery box/holder for a Honda Odyssey and a new battery, which is larger and will directly replace the one in the CRV.
