The Adrenalin head unit needs different harnesses but, more importantly, does not have an internal amp. I learned this when I upgraded from my 04 Audiophile in-dash 6. Even with correct harnesses installed, the Adrenalin headunit only turned on but gave no power to the speakers. It simply needed an external amp. It wasn't too long that I was overhauling my entire audio system with new speakers all-around, a sub/box, and two amps! It wasn't the plug-n-play swap that I had expected and more time and money was spent just to achieve MP3 capability (and the headunit itself looks pretty spiffy yet OEM). But I'm very happy with how things sound and haven't looked back since.
There is probably a way to make it work, like shvdnlayd mentioned above, but this was the route I ended up taking. Goodluck!
BTW, a shop installed everything for me.
