How do i change the side mirrors on my 2004 TL?

I just bought the replacement mirrors due to the brown discolouring on the mirrors due to the heating..

I am wondering if there is a manual or step by step guide that will help me replace...

 

if u search google for 2004 acura tl service manual, it will come up and u can look through the manual. 04-08 doesnt matter, same car for the most part
