You will be able to see Datacrons from quite a distance as they emit a large glow around them and shoot a beam of light into the sky. If you are very close to a Datacron you will also be able to hear the sound from them.
Datacron Locations By Planet
Taris – 5 Datacrons
White: Aim +2
Location: -1513, -255
This Datacron requires a long run around a ledge. You can gain access to the ledge at coordinates -1367, -208. At the end of the ledge you will have to jump across to the giant broken pipe. From the pipe you can jump onto the smaller pipes and walk across to the area where the Datacron is located. Drop down off the pipes onto the platform. Once on the platform, drop down again into the pipe and collect your Datacron!
Purple: Willpower +2
Start at -444, -171. Inside Dynamet General Hospital follow the hallway until you reach the big room. From there will be a door on the first floor on the right side. It’s blocked by debris which you can climb over to get through. Then follow the hallway until you reach your Datacron.
Orange: Cunning +2
Location: 1045, -188
Start at 1184, -168 by going up a pipe and jumping off onto the platform. From there head left toward the metal beam that bridges the platform you are on to a smaller platform. Run across the beam to the smaller platform. This brings you to a fork in the road, go right and jump onto the next (larger) platform. Head straight until you see another wall platform. Go down the path and jump off onto another metal beam. Follow this path all the way until you reach your Datacron. Be sure to hug the wall so you don’t fall off.
Red: Strength +2 (Unlocks Galactic History Entry #25)
Location: 1187, -137
Start at 1118, -150 and just jump and follow the pipeline path to the Datacron. Very easy to get.
Green Matrix Shard
Note: THIS REQUIRES TWO PEOPLE. In the Power plant at 1062, -187 stand on top of the big ventilation box that is closest to the button and have someone press it. If you’re lucky you will land on top of a pipe where you can run towards the Datacron. The only hard part is positioning yourself so that when you jump to the Datacron platform you won’t fall off. It takes a few try’s so don’t get frustrated.
