I'm not trying to be offensive but it might be time to get some local professionals involved. If the amp isn't turning on and you've got 12v from the battery in the positive terminal, ground to ground and the blue/white to the remote lead of the amp. I havne't installed a newer Pioneer in a few years but the parking brake should go to the wiring for the parking brake so that the radio will limit some functions when the parking break isn't on. If I were you I would've gotten the harness from David, svxDc and you can check his site for some additional wiring information.
