I have installed SQL server on server (nvsql01) with the following features:

1. Database engine services
2. Analysis services then i installed Sharepoint 2013 under server(nvsp01) and connected to default sql instance found under server (nfsql01)

Now i want to add features under sharepoint server(nvsp01)

1. reporting services sharepoint
2. reporting services add-in sharepoint product I installed them using sql 2012 r1 but only check these features but did not ask where to add them under which sql instance so i use sharepoint management shell and type install-SSRSservices give error. so i remove them. Dear my friend is anyone can help me how to enable Bi features under sharepoint 2013. Really need to activate sql server reporting services service application.
