Installing PAC TR-7 with Alpine Power Pack with Alpine IXA-W404 [Problem]

Okay so I have an Alpine IXA-W404 Head Unit that I got off of craigslist and installed awhile ago. Not realizing I needed to attach 2 wires to the foot brake and hand brake leads to get full functionality of the menu and options I installed it anyway. After recently doing some research I bought a PAC TR-7 to bypass the Alpine video procedure so I dont need to wire to my foot brake and hand brake leads. Well I also have an alpine power pack that I wanted to install at the same time so I dont have to take apart my dash multiple times. I tried to install it already but i'm having problems getting the PAC TR-7 to work, but the power pack is working properly. I think the problem might be that the power pack doesnt have a yellow/black wire (for the foot brake lead), but it does have a yellow/blue wire (for the hand brake lead). Since it doesnt have a yellow/black wire im not sure what to connect to the PAC. Where the yellow/black wire is supposed to be, there is an orange wire so I tried wiring that to the pack but it didnt work. Here is how I have it wired:

Headunit-->TR7's green wire tapped into alpine blue wire on power pack, TR7's red tapped into alpine red on power pack, TR7's black wire tapped into alpine black on power pack, the TR7's blue wire to alpine power pack orange, and the TR7's white to the alpine power pack yellow/blue.-->And then the Alpine to Mazda wiring harness is going from the back of the power pack into my car.

Like I said the power pack is working great, it's just the PAC that I cant get to work. I bought it new so it's already programmed and the programming switched is turned to the off position.

Please help me I have been stuck on this project for a few days and my dash is still torn apart.

I'm new to these forums so I appreciate any help!!

Thanks!,

bump, does anyone have ANY idea where I'm going wrong??? I really need to get this fixed my car is still torn apart //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

 
yeah see thats where Im confused because the powerpack is coming directly from the head unit.. so thats why I tapped 3 wires from the PAC into the power pack and the other two wires I disconnected from the powerpack

 
Yeah i installed a tr7 for my brothers 900 headunit. I hooked the wires up to the back of the headunit. Had no trouble and works great. Not sure why the power pack would have wires for hand brake and foot brake. If it did and they were hooked up would the power pack only work when you were in park? Dont think you would want that. Its probably a pain but i would take the headunit out and install the tr7 to the headunit.

 
The power pack is basically a plug and play amp. designed so you can just plug the power pack into the head unit. and then plug the wire harness that went into the back of the unit, into the back of the power pack. so i believe I have it hooked up right cuz the power pack is working properly, Just not sure why the tr-7 isnt working
