Since this is called Immersive Integration, I think you should add more integration for more mods. I just randomly thought how cool blue and green wires would look, and came up with this idea. What do you think? The connectors could have these stats:

Manasteel:
Max Range: 32
Max transfer: 16324 RF/t
Max in/out: 2074 RF/t
Power loss: 0.02

Terrasteel:
Max Range: 32
Max transfer: Infinite RF/t
Max in/out: Infinite RF/t
Power loss: 0.005
