3rd Person to First Person Camera

So I have a script that will switch between cameras, but I'm not sure how to get camera #1 (first person camera) attached to the '3rd Person Controller'. Even if I managed to get it to work, the control scheme would still be set for third person controls. So I guess what I'm looking for is a script that allows me to move from third person camera and controls, to first person camera and controls. EDIT: If I select camera 2 in the script as the camera from First Person Controller, I can switch over to that, but the third person controller object stays there, and obviously doesn't move with me in first person.

What I have currently is:

 using UnityEngine;
 
 using System.Collections;
 
 
 
 public class SwitchCamera : MonoBehaviour {
 
     
 
     public Camera camera1;
 
     public Camera camera2;
 
 
 
     // Use this for initialization
 
     void Start () {
 
         camera1.enabled = true; 
 
         camera2.enabled = false; 
 
     }
 
     
 
     // Update is called once per frame
 
     void Update () {
 
         if (Input.GetKeyDown("2"))
 
         {
 
             camera1.enabled = false;
 
             camera2.enabled = true;
 
         }
 
         if (Input.GetKeyDown("1"))
 
         {
 
             camera1.enabled = true;
 
             camera2.enabled = false;
 
         }
 
     }
 
 }
