Need Help Completing Capture a Ship Tutorial

[Reposter]

Hi guys, I am at the Antigone Memorial System and the game asked me to use the Capture Ship Tutorial. It guided me to an empty Sentinel Ship. I use my space suit and try to find the signal to decrypt the security systems but could not find it despite searching for 2 hours!

Can someone post a video or pictures to help find the location to decrypt the security systems of the ship of a Sentinel ship? Thanks, please help!
