wiring problems

ok just to make sure i am not just going blind here. on a 2000 chevy impala i am trying to locate the orange or brown acc. wire that is from the ignition but with no avail i can't find it. any suggestions?

one other question.

so all i should need to do is put a 480 ohm resistor on the lock side and nothing on the unlock side and tie them both into the same ORANGE / Black wire?

• The wires you want for the main connection are located in the ignition harness which is located at the far right of the steering column, behind the ignition switch.
• Lock and unlock use the same wire. Lock requires a negative trigger with a 470 ohm resistor in-line. Unlock is negative trigger. Must use relays.   The wire is located at a gray 24-pin plug @ BCM.
• The BCM is located above the brake pedal. It is a plastic box with three plugs that face the firewall.

ok let me know if i confuse anyone. the installation book for the alarm states that on the door lock connector has 3 wires green, red, blue. it says that green puts out a (-) Lock, (+) Unlock, red is 12v (+) output "not used" and blue  is (-) Unlock, (+) Lock. 

The door locks on the car are (-)

which way do i need to hook up the relays and do i need to use diodes?

• ORANGE / BLACK on Impala -------BLUE wire on alarm unit
• ORANGE / BLACK on Impala -------GREEN wire on alarm unit with a 470 ohm resistor in-line
• ----------------------RED wire on alarm not used because the Impala uses a (-) type A door lock system.
• No relay is required for this if you Diode Isolate One Wire With The Band Facing Towards The Alarm/Remote Start Module

i appologize for repeating myself. but you never can be to sure.

put resistor and diode on the  green wire

nothing on the blue wire

connect both wires to the ORANGE / black

i've done a few of these using audiovox brand alarms. ive used 560ohm on lock ( - ) and diode facing alarm brain on the lock ( - ) of the alarm.
