Engine Blocks & Cables [Updated IDs]
They are the glowing red bits on the back of the engine above. It also adds wall cables. Original textures belong to the creators of Retex[community.playstarbound.com] (NOTE: Retex is outdated) and Hull Plating Blocks & More (as this is a simple rework). The engine blocks are colourable.
The blocks can be found at the industrial workbench under the names "Sloped Engine Block, Engine Block, and Wall Cables", and they are compatable with Hull Plating Blocks & More.
The drive in the middle of the engine is from the excellent and amazing Placeable Dynamic FTL Drive mod that you should totally check out if you are an avid shipbuilder. The structure of the ship was built with the Avali Triage Race mod and the Elithian Races mod with the use of MadTulip’s Spaceship Mod.

The wall cables are now colourable. Red is the same as the default colour.
