yes. what I am talking about is optional. you can leave it stock. as for 90% of the cars on the road.
we must not be talking about the same thing. I don't see how installing a relay to replace something the factory did is mandatory. The fuel pump functions just fine with the factory installed harness. the coil functions just fine with the factory harness. the modification is an attempt to get "better" "cleaner' and even "more" power by getting it straight from the source, with a fresh, usually heaver gauge wire in an attempt to get more performance out of the fuel pump and/or coil. It lets you bypass any harness issues you would have, even if it is just a 20 year old wire, allowing you to get the most out of the pump and the coil. but neither of those would be "mandatory"

and having to do a list of bolt ons isn't installing e-fans the "right way"

shrouds, relays, temp controls, these things are the right way.
everything is is a determining factor in whether or not the e-fans are worth it or not.

so in essense, if you don't have the charging capabilities, then you don't need/shouldn't have e-fans, which was the whole point all along.
so in your attempt at an elitist, only you know how to "do it right" attitude, you proved the point that everyone was trying to make.
a clutch fan is the far better option when compared to e-fans given the lack of a significant performance gain and the huge cost associated with the install.
