Mixed Signals

 is a quest in the Fallout: New Vegas add-on Dead Money.

This quest starts after you complete the quests: Find Collar 8: "Dog", Find Collar 12: Christine and Find Collar 14: Dean Domino, and have gathered your team at the Fountain in the center of the Villa. The objective of this quest is to escort Christine to the Puesta del Sol switching station. Once there, she can use her computer skills to reroute the Villa's power as part of Father Elijah's plan to activate the Gala event, which in turn will open the doors of the Sierra Madre Casino.
 * This is one of three quests where you place your team members in specific areas of the Villa. The quests can be done in any order.

Quick walkthrough

 * Go with Christine to the Puesta del Sol switching station.
 * Once inside, use the fuse box near the entrance to restore power to the station and open the locked interior door blocking your way.
 * You can repair the fuse box with a Repair of 60, or use 3 of the Electric Box Fuses found in various locations in the Puesta del Sol area (see Detailed Walkthrough below).
 * Once the door is unlocked, make your way through to the station, dealing with the radio speakers you find along the way.
 * Enter the main station area and turn right, following the walkway. Your destination is the staircase across the broken walkway to your left. Get to the base of the staircase and go up.
 * To your right the walkway leads to a Dean's Electronics.
 * Follow the walkway left and enter the room. Inside, Ennis's locker contains the Remote maintenance terminal password.
 * Open the next door. There is a security turret to your right at the end of the walkway. On the wall to your left is a shielded speaker, which can be deactivated in the next room.
 * Make your way along the walkways and through the rooms ahead until you reach the maintenance elevator and remote maintenance terminal. Christine will initiate a conversation.
 * Decide to send Christine down in the elevator, or find a way to access the remote maintenance terminal.
 * Talk to Christine again to complete the quest.

Detailed walkthrough

 * Talk to Christine and ask her to go with you to the Puesta del Sol switching station.
 * Head west from the Fountain, following your Pip-Boy marker, and make your way through the Puesta del Sol to the Switching Station.
 * Once inside, use the fuse box to the left of the entrance to restore power to the station and open the locked interior door blocking your way. (The fuse box will also power up the nearby computer terminals in the same room).
 * You can repair the fuse box with a Repair of 60 (there is a Fixin' Things on the large box to the left of the locked door), or use 3 of the Electric Box Fuses found in various locations in the Puesta del Sol area.
 * There is a fuse in the same room, in a toolbox near the computers to the right of the locked door.
 * Exit the station and go right, into the Cloud. There is a fuse in a toolbox on the floor.
 * Also from the station exit, turn left instead and go down the wide stairs, turn left under the archway and keep going left until you are able to turn right. You should see a well-lit opening into a building. Enter and proceed to the top floor. Make your way out to a balcony, where there is a toolbox containing a fuse.
 * Once the door is unlocked, make your way through the station, dealing with the radio speakers you find along the way. Check the walls for graffiti pointing out some of their locations. Christine's Signal Interference perk gives you plenty of time to find or run past them.
 * There is one speaker to the right of the door as you go through, partially hidden behind the pipes. Another is high on the right-hand wall of the alcove you pass, to your right, in the same corridor. There is a third speaker around the corner and down the stairs, well hidden under the pipes high on the left-hand wall. All three can be destroyed with weapons, but not otherwise deactivated.
 * Enter the main station area and turn right, following the walkway. Christine will draw attention to the cloud below you. Your destination is across the broken walkway to your left. Below you is a large pipe which can be jumped on and run across to the other side of the room. You can then jump to the base of the staircase and go up, thereby avoiding most of the cloud.
 * To your right the walkway leads to a Dean's Electronics. It is protected by a shielded speaker, but Christine's Signal Interference perk will once again give you enough time to run around the walkway and reach the terminal to deactivate the speaker. Watch out for the tripwire just in front of the terminal; you can disarm it quickly, or carefully access the speaker terminal and then deal with the trap. Note that the tripwire may already be disabled (or have gone off, possibly moving the Dean's Electronics book) when you enter the building.
 * Following the walkway left from the top of the staircase leads to a door into a small room. Along one wall are some lockers, including Ennis's locker which contains the Remote maintenance terminal password. The lock can be picked with Lockpick 100, or opened with a key which is found in the same room on a desk with a working terminal (in the far right corner as you enter the room). Also in this room, a terminal contains messages related to the History's Sake challenge. You can also choose to activate the ventilation system from here. Doing so will clear the poison cloud from lower levels of the switching station and from some areas outside in the Puesta del Sol.
 * With the cloud vented, you can go back down the stairs and safely explore the previous room for a few spare Sierra Madre Chips and a skill magazine, some ammo near the middle of the room, two Stimpaks atop the two big metal boxes next to the ammo and toolbox. A corpse can be found behind a fallen piece of walkway (below the entrance walkway), wearing a Dead Money jumpsuit and carrying the See you in hell asshole note. Watch out for several bear traps under the large pipe you crossed earlier.
 * The door out of the room opens to reveal another walkway. There is a security turret to your right at the end of the walkway, and a shielded speaker on the wall to your left. The turret can be targetted and destroyed from inside the room you are still in, safely out of range of the speaker. Directly across from you is a locked door Lockpick50, behind which is the terminal to shut down the speaker. You can also choose to follow the walkway around to the right and access the terminal from the open door on that side.
 * With the speaker deactivated you can safely return to the walkway. Jumping across to the broken platform in front of the speaker and turning left will lead you to a Chinese Army: Special Ops Training Manual (follow the left-hand catwalk around the machinery).
 * Proceeding from the room with the speaker terminal, continue until you reach the maintenance elevator on your left. Across from it is the remote maintenance terminal. Christine will approach you and initiate a conversation, expressing her fear and unwillingness to enter the elevator. With various dialogue options you can deduce that she is remembering her experiences trapped in the medical clinic auto-doc, and is showing signs of claustrophobia (and possibly post-traumatic stress).
 * Your choice at this point will affect Christine's actions later in the game.
 * You can choose to lie to Christine and trick her into the elevator. This will complete the quest.
 * You can tell her you will look for another way to access the station controls.
 * You can now search the area more thoroughly. Opposite the maintenance terminal (to the right of the elevator) is the vending machine code for the Holorifle reinf. components, on top of a computer. Accessing the elevator and going down will give you a written on-screen description of a tiny cramped room full of whirring machinery, exactly as Christine feared. Going up in the elevator leads to an exit back to Puesta del Sol - an upper floor room overlooking the street. There is a Fixin' Things on a desk to your left, an Absinthe behind a pipe above you, and random items in the containers.
 * To help Christine you must gain access to the remote maintenance terminal. You can hack it with a Science of 100, or use the Remote maintenance terminal password you discovered earlier.
 * Talk to Christine again and tell her the terminal is useable. She will express her gratuitude and offer her hand in friendship. Once the dialogue ends she will take her seat at the terminal and the quest will be completed.
