If you check out part 43 in the appendix it will list what's considered a major alteration. I think what we are discussing doesn't qualify as a major alteration at all, assuming it is just a simple installation that doesn't require a redesign of the whole electrical system (you know how projects can get out of hand) but many mechanics just want to cover their tail all all costs.
