Pinky on E string 7th fret, ring on G string 6th fret, middle on C string 7th fret, pointer on A string 5th fret. To switch, take off you middle and pinky and use your ring to bar the top three strings. So it will be your ring finger on G C and E 7th fret, and your pointer on the A string 5th fret. If I'm wrong about the chord shape let me know.
