Eyesight to the Blind

 is a quest in Fallout: New Vegas.

Quick walkthrough

 * Speak with Elder McNamara after completing Still in the Dark to activate
 * Follow map marker to Black Mountain.
 * Meet with Neil. If you pass a speech check (50), he will aid you.
 * Walk through the gate and wait until it says you discovered Black Mountain. Then, find a safe place and fast travel there. You can bypass many of the enemies in the next step.
 * Defeat the enemies along the way to the summit (supermutants and nightkin).
 * Enter the broadcast building (building with satellite on roof)
 * Exit door in rear, retrieve Tabitha's key under stairs
 * Go up stairs to second floor of broadcast building
 * Deal with Tabitha, a supermutant inside the door, one of two ways:
 * Kill her
 * Repairing Rhonda, a broken Mister Handy on a table, inside the storage room (60 Science required). If you resolve the quest by repairing Rhonda, make sure you get Tabitha's room key.  If you don't, you need to pickpocket from her in order to gain access to the 2nd floor of the broadcast building where the terminals to be bugged are.  This must be done before she walks away, or she will leave to travel the wasteland and be difficult or impossible to find. (There is also a spare key under the stairs behind Tabitha's building)
 * Place the Remote Signal Transponder on one of the Terminals.
 * Return to Elder McNamara

Detailed walkthrough

 * To start this quest, you will have to leave the bunker and go back to Elder McNamara. After you complete the quest Still in the Dark, Elder McNamara will ask you once again for your help. Accepting his request will activate . NOTE: If this quest is unavailable to you, you may have to complete Veronica's quest, I Could Make You Care. This is more likely if Veronica is your follower.
 * This quest becomes very easy if the player has already completed Crazy, Crazy, Crazy beforehand, as there will now be little or no oppostion at Black Mountain (be aware of the random Nightkins that will keep spawning near the radio center). (PS3) In some cases, if you return to Black Mountain after having completed Crazy, Crazy, Crazy, you will be met with around ten Super Mutant Masters and a few Nightkin masters.
 * Elder McNamara will give you a Remote Signal Transponder. He will ask that you head to Black Mountain and place the transponder in the broadcast building at the summit. Black Mountain is located near Hidden Valley to the north
 * After you pass the crater you will find a gate, open the gate and a friendly supermutant name Neil will stop you and ask you what you are doing there and warn you of the danger ahead
 * If you pass a Speech check (50), he will aid you in your quest. It is recommended that you have Neil help you since the supermutants are formidable opponents.
 * If you don't have the necessary skill, you must make your way up Black Mountain without him. Neil will be located to the Southwest in a shack.
 * Once you've cleared your way up the mountain, there will be a village with a crater in the center. There are 3-4 more Supermutants here. Neil is behind the Dome structure. The dome has two trunks in it, one with an average lock on it, normally containing a Minigun.
 * Talk to Neil again and he will create a distraction for you to head up to the Broadcasting Station. There will be a Nightkin Sniper and several leveled Nightkin outside the buildings. The storage area has a treasure hunt inside. Take the note on the dummy, which asks you to find: 1 Missile Launcher, 3 Missiles, 3 C-4 Plastic Explosives, 5 Frag Grenades and 1 Super Stimpack.
 * Head to the radio center, enter, and exit through the rear. Grab the key below the stairs, near some rocks, and head up the stairs.
 * Tabitha will be inside the second floor room (unless you have completed Crazy, Crazy, Crazy). There are 2 ways to deal with her:
 * Reactivate Rhonda, a broken Mister Handy, in the storage room (Science 60 required).
 * Kill her (can be killed after reactivating Rhonda and ending the Crazy, Crazy, Crazy quest peacefully)
 * Attach the Remote Signal Transponder to a console in the upper level of the radio center.
 * Report back to Elder McNamara, he says they have been receiving telemetry from the transponder. He will reward the title of Brotherhood of Steel Paladin, T-45d Power Armor in poor condition, the perk Power Armor Training, and full access to the armory.

Bug
* If you reunite Rhonda and Tabitha before you have installed the radio signal transmitter, Tabitha may attack you after Radio Control Room 2. Rhonda will have disappeared. Confirmed on Xbox360 and PS3 set "000E327C".LockdownLifted to 1
 * Trying to validate the quest when Elder McNamara is at the entrance will stick your character. You need to wait for Elder McNamara to go back to his office room and sit.
 * If this does not work, the following will: if you get stuck talking to the elder about training at the bottom of the stairs... don't talk to him. just push him all the way back up against the L2 door in the basement, stand close to him in a way that when you look straight up it gives you the option to open the L2 door and when you look down it gives you the option to talk to the elder. don't move from this position. talk to your elder, get yourself stuck during the conversation and then select to open the L2 door. it will go black and then come back with you standing at his desk with power armor training intact and the glitch over with.
 * 2nd solution: When McNamara is stuck in the entrance and waiting doesn't help open console and click on McNamara (so his ID appear at top of the screen) and type ResetAI . After this he went to the control room and I was able to get Power Armor Training there.
 * 3rd solution: You can use the console command "prid ref-id" to select "ref-id.moveto player" to spawn him near you (without quotes and reference id is McNamara's in this case) if other two solutions did not work for you.
 * After completing Still in the Dark both the elder and Hardin will not talk. Even if you wait 8 days or more.
 * Solution: Exit the Hidden Valley area and return later. Make sure all other BoS quests are done. Lockdown lifting will be prevented by staying inside. Other solutions needed.
 * When you try to complete the quest your character becomes stuck and only has control of the vertical move of the camera.
 * A Great Khan may randomly spawn behind the elder.
 * After completing the quest this user lost all reputation (idolized) built with NCR, if experienced reloading a previous save might solve issue
 * To force the lockdown to be lifted after all other BoS quests are concluded, open the console and enter the following command. After this, the elder will speak to the player again, opening the way for this quest to begin.
