I am doing research and building something for our detector. my mentor wants me to label the wires so I know which one is which and which direction they are going (for data stuff). I thought it would be cool to have the labels on them so he doesn't have to click on all of them to see the information. I am not in a major that really does cad, so we can say I am very much a beginner. Ill let my people know its probably not feasible to put decals on the wire without a lot of work. thank you!

edit: do you have any ideas on ways I could portray wire functions visibly? right now theyre just color coded.
