This is for the people who do wan tto attempt this and have the talent. Is is a guide for them to follow. If you do not wish to use this solution, then don't do it - I would never recommend this to a novice. This is definitely a lot more than installing a stereo - you need more experience than this. It is risky, but with risk comes great reward. Bottom line: I would not recommend this to anyone who does not have the experience required to perform the wiring - if you have to ask yourself, then I would not attempt it.
