I think what GM has produced is pretty good. You've got to remember that it's a universal loom and potentially has to fit a lot of different styles of installation. These motors are going into all kinds of vehicles and not all with the standard intake setup.

I think most of the people on here are DIY types. You wouldn't even contemplate taking on the build of a Cobra without having some skills or desire to learn desire the skills to build one.

It comes down to price. Yes, a custom installation is nice but how does it compare in price to an off the shelf loom you can plug in yourself? I imagine you start with a donor loom to wire up a car. That's what I did, I bought a new Commodore loom from Holden for about $450 and then stripped out all the unnecessary wiring and shortened it to suit my application.

Most people seem happy to mess around with suspension, welding, fabricating and bolting things together but look at wiring as if it's some dark art. In the days of just a carburetor and an ignition and charging system to get it running most would have a go themselves. Suddenly EFI is here and seen as just too hard. In reality it's not that different. If you read the books and take the time to understand what the components of a system do and how they work together it's not hard. There are plenty of wiring diagrams and resources available for anyone wanting to have a go themselves. Take the challenge to learn something new.

I think it might be worthwhile to start a thread on here explaining the basics of how an Electronic engine management system works.
