I'm trying to build a rocket with sugar engine. The engine shows the warning "No electrical consumers", but there is no obvious way to connect anything to it: it doesn't have any electrical connections. There are no electrical connections in the capsule/nosecone for that matter.
1. Build Rocket platform.
2. Build Sugar engine on top of it.
3. Observe "No Power Consumers" warning
4. Go to Power Overlay
5. Observe no power connections on the module.
