Trouble disabling and enabling components on charactercontroller

Right now i'm trying to get unity working with the photon multiplayer asset, and I think the tutorial i'm following makes it work by disabling certain elements of the characterController on startup, and enabling them on spawn so it only works for your individual characterController. I'm using a characterController my friend has altered, and i'm having trouble with disabling/enabling elements of it. This is what it looks like in the hierarchy, this is what i'm trying to disable and re-enable.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;

 public class greenchickenstartserver : MonoBehaviour {

 public Camera SpawnCamera;
 void Start () {
     PhotonNetwork.ConnectUsingSettings("v4.2");
 }

 // Update is called once per frame
 void OnGUI()
 {
     GUILayout.Label(PhotonNetwork.connectionStateDetailed.ToString()); 
 }

 private void OnConnectedToMaster()
 {
     PhotonNetwork.JoinLobby();
 }

 void OnJoinedLobby()
 {
     Debug.Log("OnJoinedLobby");
     PhotonNetwork.JoinRandomRoom();
 }

 void OnPhotonRandomJoinFailed()
 {
     Debug.Log("OnPhotonRandomJoinFailed");
     PhotonNetwork.CreateRoom(null);
 }

 void OnJoinedRoom()
 {
     Debug.Log("OnJoinedLobby");
     SpawnMyPlayer();
 }
 public Camera camera;
 void SpawnMyPlayer()
 {
     
     ///PhotonNetwork.Instantiate("newcharactercontroller", new Vector3(22, 14, -47),Quaternion.identity, 0);
     GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate("newcharactercontroller", new Vector3(22, 14, -47), Quaternion.identity, 0);
     SpawnCamera.enabled = false;
     ((MonoBehaviour)myPlayerGO.GetComponent("First Person Controller")).enabled = true;
     ((MonoBehaviour)myPlayerGO.GetComponent("Camera")).enabled = true;
     myPlayerGO.transform.Find("FirstPersonCharacter").gameObject.SetActive(true);

 }

}
