arm and disarm factory alarm, 04 mdx?

Hi all,

I have a Compustar CM3000 Remote starter and Alarm on my 04 Acura MDX.  I connect the arm and disarm wire from the CM3000 to arm and disarm the factory alarm and I run those 2 wires power lock connector on the driver door, bule/white for arm and RED / black for disarm.  I follow this thread to connect the arm and disarm wire and I don't think I miss those 2 wires.

The problem I have right now is when I lock the car with the Compustar remote, the Red LED by the driver door won't blink (this LED blink when I lock the car with the factory remote), it give me the impression that I did not arm the factory alarm. I was able to start the car fine but the factory alarm went off occasionally when I start the car and I can't disable the alarm with the Compustar remote, I have to open the door with the key to stop the alarm.

I'd appreciate if somebody give me an advice how to fix this problem.

Thanks,

Arm/disarm are INSIDE the drivers door at the lock switch..... is that where you got em?

Arm is blue/white disarm is blue with silver dots

Thank you for your response,

Yes, I got the arm/disarm wire inside the driver door and at the lock switch, arm is at pin 6 and disarm is pin 16.

I have to take a look at the arm/disarm wire agian this week.  But one thing bother me was if I did not connect the arm/disarm wire correct then how can I start the car ? as far as I know if I don't disarm the factory alarm, it would not let me start the car.

One more thing I noticed was, I was able to start the car while the door is I locked  w/o triggering the factory alarm and the only time the factory alarm trigger was If I locked the car and let it sit there for a whole day.

Thanks again,

Thank you for your response,

Your advise is really helpfull and It would be nice if I had known I can use the lock and unlock wire for arm/disarm before I start the installation.  It'd have saved me half of the time I spent for installation.  It's really painfull to take off the door panel and run the arm/disarm wire from the driver door through the wire boot.

You are right, I did not arm and disarm the factory alarm since the LED on the driver door never lit. 

I used the BLACK/ orange wire for Lock and Blue/orange for Unlock (located in the Pass Mux Unit with the horizontal connector as you mentioned).  The only thing I need to do right now is connecting the arm/disarm wire from the Compustar to the Lock/Unlock wire. I don't think I need diodes for isolation but for safety purpose, I'll put 4 diodes at the output of Lock/Ulock, Arm/Disarm of the Compustar.

Thanks again.

I've just got the arm/disarm wire connect to the door lock/unlock wire ( BLACK/ orange, blue/orange) with 4 diodes and still, it wouldn't arm the factory alarm.

The LED on the door would not blink when I use the Compustar to lock the door.

Any other suggestion ?

Thanks,
