What do YOU want in a new wiring harness?

Yes, makes sense from a consumer or installer's stand point.
Now please try to look at it from a supplier's or manufacturer's stand point. All of your ideas are perfectly acceptable. But could be difficult to cost effectively implement in the production side. Which is why i said i wouldnt argue or say any suggestions are wrong. Am trying to find some middle ground between the two sides. Some things would be very difficult to make everyone happy on.
Mayb i'm looking to start a new buisness, or improve an existing product...either way all is taken under advisement.
