If you want the official manual you can download it here for about $10.
Sidecars are all setup the same way so you can find several setup write ups like this one or this one for free if you'd like to use one of those instead. It's never a bad idea to have the factory manual though.
I hope this helps. Please let me know if I can be of further assistance. Also, please leave a positive rating for my service today. Thanks, P.J.
