Eyesight to the Blind

Eyesight to the Blind is a side quest in Fallout: New Vegas.

Detailed walkthrough
This quest can only be started if the player has completed the quest Still in the Dark for the Brotherhood of Steel. The player then has the option to ask Elder McNamara to join the Brotherhood. Elder McNamara will tell the player that though outsiders cannot normally join the Brotherhood, membership has been bestowed upon those who complete a heroic act in the name of the Brotherhood. He then informs the player that he does have a specific act in mind; install the remote signal transmitter in the radio station atop Black Mountain, controlled by hostile super mutants under the rule of Tabitha. Accepting his request will activate this quest.

Ascending Black Mountain
Reaching the peak of Black Mountain, and entering the broadcast building can be a daunting task as there are super mutants guarding the winding pathway up the mountain. See Crazy, Crazy, Crazy for a detailed description of ways to ascend Black Mountain.

Planting the transmitter
Once Tabitha has been dealt with, or the player is ready to eliminate her at close range, enter the broadcast building, then exit through the opposite door to access the fenced-off rear area. Grab the key hidden in a false rock under the staircase, and enter the building. If Tabitha has not been dealt with at this point, the player must combat her inside of the building.

At this point, the player must activate the main broadcast control board, and plant the signal transmitter.

Conclusion
Once the remote signal transmitter has been planted, the player must return to Elder McNamara. Once the player has informed the Elder of their deed, they are immediately inducted into the Brotherhood of Steel, and given a suit of T-45d power armor and a matching helmet. If the player does not have the Power Armor Training perk, Elder McNamara teaches them how to use power armor.
