how to install wiper moter

I'm not sure how you would be installing them wrong; I do know that when you buy a wiper motor from the dealership, it often comes with a wiring harness that has to be spliced in to operate. Not sure where your wiper motor is being purchased from.

Instructions for installation can be got at Alldata. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
