Wire Connections

[AutoNub]

Hello. I'm working on creating a wire harness, and there are a lot of components and thousands of wires. After a couple days the wires begin getting so abundant that I run out of room for new wires (so I have to frequently reorganize things to create more space, which can be very time consuming). I'm curious if there is an easier or more simplified way of drawing wire connections. Do they need to be wires connected via lines from one pin to another, or can I simply tag one pin with a wire name and another pin with the same wire name, so my Autodesk Inventor import will still be able to automatically route all of my wires? It'd be faster and far more organized if I could simple tag each pin with a wire designation, so I could avoid drawing the wires themselves and having to constantly reroute them.

Thanks in advance for the tips & information.
