99 ford mustang w/premium audio issue

Last week I had to install an aftermarket Pioneer stereo in my Mustang that has the premium audio w/ one amp.  Eversince the radio has been installed, my battery keeps going dead.  I am suspecting that the factory amp is always on and is causing the battery drain issue.  My question is, what wire am I supposed to use for amp power that is not consistant coming from the factory wire harness, to the crutchfield wire harness then to the harness that comes off the back of the Pioneer head unit?

Here is the stereo that I purchased:

I got this wire harness from Crutchfield:

Harness #1 Power

Harness #2 Speakers

Factory wire harness:

A resistor did not come with the wire harness from crutchfield.  I took the head unit back out and here is what I have connected:

Factory Harness------------------------------------------Crutchfield Harness-----------------------Pioneer Headunit Harness

Lt. GREEN/ Violet (12VDC Battery)---------------------Yellow (12VDC Consistant)-------------Yellow (12VDC Consistant Battery)

Black (Ground)--------------------------------------------ORANGE / Black (Ground)-------------------Not connected, taped off

BLACK/ Pink (Swtiched Accessory)---------------------Red (12VDC Ignition Switched)--------Red (12VDC Switched Accessory)

Lt. Blue/Red (Illumination)------------------------------Orange (Illumation)------------------------Not connected, taped off

GREEN/ Black (Ground)------------------------------------Black (Ground)-----------------------------Black (Chassis Ground)

ORANGE / Lt. Blue (Remote Turn on output)----------Blue (Power Antenna)--------------------Not connected, taped off

Blue (Mute)--------------------------------------------------Blue/White (Amp Turn On)--------------Blue/White (System control of power amp or auto-antenna 12VDC Switched)

 When fuse number 27 in the central junction box under the dash for the amp is plugged in, my speakers work and eventually the battery will run down.  When the fuse removed, the speaker will not work and so far the battery has not ran down with the fuse removed.

With the wires connected as the diagram above, I have to have the Blue (mute) wire from the factory harness, connected to the Blue/White wires coming from the crutchfield harness and the head unit.  I connected a test light to this wire and the blue (mute) is a switched wire, when the ignition is on i have power on that wire, when the ignition is off or the head unit is off, i have no power.  So to me that is working correctly?  The ORANGE / Lt. Blue (remote turn on) wire does not have any power.  Yellow has consistant power no matter what position the ignition is in, and the Red switched accessory only has power when the car is running or ignition is on accessory.

If i leave fuse 27 in and measure for power there at the fuse box, i have consistant power on fuse 27 no matter what position the ignition is in.  This is what led me to believe that the amp is always on and causing the battery to run down.  The battery did not start to run down until a few days after the new head unit installation.

Do I have this wired correctly, or do I have something wrong that is causing something to stay on, therefore causing the battery to run down?

When I disconect the blue/white wire from the blue wire coming from the factory harness, the sound goes away.  The yellow wire has a consistant 12V, the red wire has power when the ignition is on or switched to the acc position.  When I measure for votage on the blue/white wire, it seems to only have power when the head unit is turned on.  When i have the car started and the radio on, I have power on the blue/white wire, with the car still on and if i power off the head unit, I do not have power on the blue/white.

Should I connect the blue/white wire to the red switched wire?

ok the wires are right so that shouldnt be the problem. maybe you have a defective radio or maybe its something in the car that went bad and its just coincidence that it happened after you installed the radio. the other thing you could try is to isolate the remote wire from the car by running it through a relay switch. by using a relay you can completely separate the  remote wire from being connected to the car when the car is turned off. do you need me to explain the relay or do you already know what im talking about?
