How do I put my suspension from IPGKinematics in my vehicle model?

Hello,
I have created an .kin file in IPGKinematics for my DoubleWishbone Rear Suspension, but I cannot understand how can I run it in my vehicle model (Parameters>Suspensions>Kinematics). Should I make an skc file? How do I make it? Should I do something different?
Thank you for your help!
