Just watched some x-wing tips on flying Vader on youtube and there's something I am missing.

In the video, he attached an engine upgrade to the TA. I thought the bar had to have the (crossed wrench) icon in it. It doesn't.

Obviously, that icon can be used on any ship, but where does it state that?

EDIT: annnnnd... I found it on the Modification and Titles Reference Card, plus I am assuming that because the bottom left corner of the upgrade card (face up) has no icon, it can be used for any ship.

Any ship can equip just one Modification card. No icon required on their action bar.

Unless its a TIE Interceptor with the Royal Guard TIE title card, then it can equip two.

And, they must be two separate and different mods...

Stealth and Hull seem quite nice together.
