Tilting Head with Camera from the FirstPersonController Script FPS controller provided in (Unity 5)

Hello All,
I am using the provided FPSController prefab provided with Unity 5 in the character assets.
(I was making my own first person camera script but this provided more options)

I wanted the camera to effect the head bone of my character model.
I want my character models head to tilt where I am moving my camera.
What can I add to the script to do this?

Thank you for your time in advance!

Ok Figured out how to Rotate the neck with the camera (The example below I had to have the X of the camera rotate the Z of the bone)
Put this Script inside the head bone of your character:

using UnityEngine;
using System.Collections;

public class HeadTiltWCamera : MonoBehaviour
{

    public Camera cameraRot;
    private Vector3 objRot;


    // Use this for initialization
    void Start()
    {
        //Only take the x axis rotation
        //Bone only uses Z for up and down, camera oddly is using the X for up and down
        Vector3 tmp = cameraRot.transform.localEulerAngles;
        tmp = cameraRot.transform.localEulerAngles;
        tmp.x = 0f;
        tmp.y = 0f;
        tmp.z = -cameraRot.transform.localEulerAngles.x + 10.0f;
        objRot = tmp;

        transform.localEulerAngles = objRot;
    }

    // Update is called once per frame
    void Update()
    {

    }
    void LateUpdate()
    {
        //Only take the x axis rotation
        //Bone only uses Z for up and down, camera oddly is using the X for up and down
        Vector3 tmp = cameraRot.transform.localEulerAngles;
        tmp = cameraRot.transform.localEulerAngles;
        tmp.x = 0f;
        tmp.y = 0f;
        tmp.z = -cameraRot.transform.localEulerAngles.x + 10.0f;
        objRot = tmp;

        transform.localEulerAngles = objRot;
    }
}

There is one problem, The camera will not move its position with the animation because OBVIOUSLY it is not parented to the head.
The problem I have when I parent the camera to the head is the Minimum and Maximum X constraints do not work and the camera will rotate on weird angles.
I suppose I should find a way to just make the neck do what the camera does with the FPS controller and have the camera move with the mouse movements. Or I could figure out why the camera is working oddly when parented to the head.

Well I figured I would post this for anyone that might be interested in this sort of thing.

I once removed the bone from the model and placed it within the first person camera… that worked
