The player must install the override module at the El Dorado substation. Several NCR troops guard the substation and warn the player that there will be trouble if they enter.
Alternatively, wearing NCR armor can cause the guards to refrain from shooting on sight.
After accessing the terminal, the player will gain Infamy with the NCR. Upon completion, return to Mr. House.
The player starts by talking to Mr. House, after The House Always Wins VI. He will explain, and the quest begins.
Exit the Lucky 38, the recommended companions are boone with any other. Fast travel - if possible - straight there.
Once there, a NCR trooper will approach you, saying to keep out. Ignore and enter the garage door (NCR armor is highly recommended as it means they dont start shooting. If you don't have NCR armor, use a stealth boy instead).
After it loads, head for the right-hand side of the building. Access the terminal and insert the chip. Exit the substation, and report back to Mr. House.
Go to the El Dorado Substation and install the override module.
