Wiring Diagram 2002 Mazda Millenia Alarm

Hi guys I'm trying to remove the factory alarm from a 02 Milly and replace it with an aftermarket w/ autostart. I'm hoping for a simple disconnect the wires from the factory box and connect them to the new one, then all i have to do is worry about the auto-start. Do any of u guys have a wiring diagram for the 02 millenia alarm.

Use DEI part number 555U. *1 Also found in a white plug in a silver box next to the firewall above and behind the fusebox: 12V-WHITE/ red; starter-BLACK / YELLOW 12awg; ignition-BLACK / YELLOW 18awg. *2 Negative trigger through a 1K (1000 ohm) resistor will lock the doors and arm the factory security. Negative trigger on the same wire will unlock all doors and disarm the factory security. Test using the passengers door key cylinder switch with all doors closed. To disarm with out unlocking, send a positive trigger to the blue/black key sense wire. The key sense wire is located at the steering column. *3 In a large harness to the rear of the car. *4 In the harness coming in from the drivers door. *5 Rest at ground with the key off. Diode isolate to keep ground from feeding back from the indicator lamp.    *6 In a 20 pin green plug. *7 The diagnostic connector is in driver side rear corner of the engine compartment. *8 The bose amplifier is behind the rear seat on the passenger side. The rear speaker wires are different on the bose amplifier. They are LR(+/-) grn/blk - grn/org, RR(+/-) yel/blu - yel/grn.Be careful whose advice you buy, but be patient with those who supply it.

Thanks for the quick reply, one last quetsion though. If i replace my factory alarm completely and keep their wiring. Will i still need the 555U, i just want to strip out my old box and replace with the new (assuming they use the same type pulses for triggers). I figure using this method, it wont be much more complicated than a head unit install, except for auto-start. Where would i look to find the factory alarm?
