what its doing, and the result are very very different. Because this whole thing came about because of some mis communication of what the illumination wire does... and its simple because of the such fast switching it really doesnt matter that it is a pwm or not. I say this because, if your hu or whatever is so primative not to have a pwm sense built in, then it likely wouldnt be able to sense fast enough this switching that is going on. It would simply "take the average" by default.

And again, the measurement (in my case) is going to be a measurement between ground that is what most meters will read since it switches so quickly. AND it can still be hooked up with the pwm removed, and resistance to ground put into its place for the entire circuit, this will allow you to control it very much the same, but with more heat lost.

its really a moot point that it is a pwm or pot type, cuz honestly, I really doubt the z1 is unable to "sense" this, and if it is I doubt that it can sense such a quick on off then. I know that the dimmer works fine with a avic-n3 and a Honda Accord 2006 because I have installed this myself and used the dimmer that way. Surely pioneer has accounted for this throughout their automotive product line.

Yep, that was my point too. I was (and some others were) saying that it was a pulsed wire. But in the end it doesn't really matter. Which is why Crutchfield doesn't go into what is actually happening. It would just confuse the masses. As long as it works the masses don't care. In the end they do pretty much give you the same result.

I think that originally the topic was brought up cause there are newer pulsed systems out there... not cause things may or may not work, just that they are different and becoming more common.

Umm wow. I can't even read all this stuff. Can we all just agree to disagree and leave it at that?
