Can someone please help me how to connect a Ragdoll arm between the controller and the camera

I have a ragdoll arm, and I’m trying to attach the hand end to the controller and the shoulder end to the side of the player camera. I cannot get this to work. I’m trying to do this with Physics Constraints, but the arm keeps spazzing out. I don’t know which part attaches to what. Basically I want to simulate the arm movement. (I know this is gimmicky, but I’d like to try it out)
