Yes, installation instructions for Curt trailer hitch # C11212 (no longer available) are linked on its product page, right hand side of the page. I have also included a link to them here for you.
This is a Class I hitch so if you are using it for a bike rack you are limited to 2 bikes at most and any accessory used has to be compatible with a Class I hitch. Also with Curt if you are using the hitch for anything other than a trailer you also have to use stabilization strap # 18050 per Curt's... view full answer...
