I have to agree with NAILS. Not only has this become an issue of "it looking like sh*t", but as I already said and others agree, this has become a matter of safety and putting someone else's life in the way of shitty workmanship. Its one thing to use different colored wires (which is stupid anyway) and do it the right way, but to do it with different colored wires and have them strewn together like that is BS.
If that mechanic is not the owner of the shop you took it to, I would be in the owner's office the second I saw that. You don't have to take that sh**, your a paying customer and that car is not reliable. If an inspector was looking at this car, he'd probably laugh and fail the car on the spot. I don't give a damn if it's a V6 or a V12, all motors follow the same principles and they can all catch fire the same way as all the others. I wish you were closer cause i would go with you to the shop and then help you clean up that rat's nest under your hood. If I were you, I would consider filing a suit against the shop.
