This page is a walkthrough for the Los Santos Tuners DLC Auto Shop Setup mission, Entry Point. It’ll navigate you through the necessary steps to successfully tracking down entrance to the IAA Base.
Find a way to enter the IAA’S Facility beneath their Los Santo’s Headquarters.
Go to LSDWP Substation / Photograph the IAA Entrance
Once you’ve activated the mission via the Job Board, take any car and head over to the LSDWP Substation. Upon arrival, wait for the guards cone on the mini-map to face the opposite direction, then sneak into the area.
Enter the first trailer on the right and take a picture of the schematics which is on the desk, then follow the waypoint to the Subway Tunnel. Continue following the track to the Central Traction, then you’ll want to take a picture of the green door to bring the mission to a close.
