What does it actually offer that is going to matter for the majority of people? Some of their biggest points were that it somehow sped up installation, that it made identifying and tracking down problems easier, and that it allows customization of how the system operates.
On the first point it has seemed to me unlikely that it would be any faster. Even comparing universal kit to ISIS it seems like I'm missing something that would make it faster and easier to install. Compared to a direct fit AAW type kit, it seems like an even more ridiculous comparison.
Identifying problems sounds good but it seems like many of the potential issues would come from the fact ISIS is a universal wiring kit and you might screw things up because it won't have instructions for your vehicle.
Customization sounds nice also but how many people are going to use any of it?
There are certainly situations where I imagine it's great, I mean if I had a car that had no direct fit kit for it, I would certainly consider it, but I think once the shine of it being a fancy thing wore off, people maybe realized that the half the cost AAW kit was a wiser move.
