alpine by-pass

Hey there everyone, i have an alpine dvd screen in my 02 alero, and i have the tr-7 bypass. and i cant for the life of me to get the thing to work, the only way i can get it to work is if i leave the hand brake wire connected, but than the thing chimes at me when i drive over 15kph, any ideas? any one experience this? also i posted earlyer that i scratched the screen during install, anyone got any ideas for that too? thanks u guys!!! really apprechiate any feedback

call a professional installer, they are usually helpful for tleling you the proper wire configuration...they helped me with mine, but i can't remember it or am i able to find the paper they wrote it on
