book ideas, car security guide?

I've thought of it...I don't know if you guys get ME mag at all, but they have a feature where they'll review a couple brand new vehicles...sometimes the DEI techs are supplying info for it, among others.

The thing there is that I'd like to get into more detail - for example, how much easier would it have made things if when the 2003 Saturn Ion or 2001 Chrysler minivans were introduced, someone in the industry wrote a thorough explanation of multiplexed ignition harnesses and how the automakers were starting to use them. Or of multiplexing in general, really.

Granted that those aren't exceptionally difficult vehicles to install on - but for those who were in the industry at the time it would be nice to have a detailed explanation to give to our customers, rather than 'the book says we need this extra part'.  And that's more info than I think could be put in a magazine article...however I could see publishing an annual update, or a detailed vehicle analysis for new models.

Immobilizers are another big thing for sure - how many customers and installers do you know who have no idea whatsoever about how they work, what cars have them, what the keys look like, and what it takes to bypass them?
