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.

You will land in near a cave. Follow the path through the cave to collect your Datacron.

This Datacron can be a bit tricky and requires some climbing. Head to coordinates 2607, -844 and start jumping / climbing up the ice. Eventually you will end up above what appears to be an ice bridge. Drop down onto the ice bridge. Follow the path as far as you can, again you will need to do some jumping / climbing. When you reach the appropriate level your Datacron will be waiting for you!

Red: Strength +4

Location: 2992, -89
To get this Datacron you must first kill the Ancient Probe Droid and loot a “depleted Datacron”. Then head to coordinates 2850, -109 inside the Starship Graveyard. You will notice some pipes on the wall, on the right hand side, start climbing up them. At the top of the pipe, jump off onto the top of the wall and follow the path. At the end of the path is another pipe you can jump down on. From that pipe you can drop down to the Coupled Recharge Station. Use the keyboard there and shazaam! Datacron!
