What is this??
1984 Porsche 944
This is right above my speed and reference sensor, and I didn't notice it was broken and the other piece next to it wasn't connected to anything until a few minutes ago. Is this important? Could it cause my car not to start?

Welcome Mike. I had the same question a few months ago. That connector is a big plug connector and the rest of the orange bit comes out of the black part. It is the connector for the O2 sensor. The other pigtail with 2 wires is only used for California cars where the O2 sensor has a heating element so the O2 sensor works faster and controls emissions better. Mine isn't connected to anything.
My connector was also broken so I followed post #6 at 944 Forum - Broken O2 sensor wire connector? to re-connect my O2 sensor. I think that it works now. Others may have other advice on re-connecting it. Good luck!

Yep O2 sensor connector. It's not really "needed", so it wouldn't keep your car from starting. Without input from the O2 sensor the DME defaults to a preset of fuel maps, which will probably cause it to run a little rich over time. Fixing my broken O2 wires has been on my to do list for years...
