Being the nice brother that I am I decided for christmas to install an alarm on my sisters 99 mazda 626. Now this will be a first time install and have been reading up on installs. I feel that I can do this. Now the only thing that I am a little confused on is the vehicle already has power door locks. How do I hook these up to the alarms? Also does anybody have a wirring digram for this car? Any other suggestions and pointers would be great. Thanks everybody.

Here's the diagram for the car: 1999 Mazda 626 Alarm Information

I'm pretty sure you can just hook up the new alarm's wiring to the door's lock/unlock wires for the keyless entry. I think removing the existing keyless entry system (I'm assuming you mean she already has power door locks and keyless entry)....would be a tough thing to do. I think I would just find the right wires from the diagram, and hook into them, and not use the factory keyless entry remote anymore. I'm sure someone will butcher my reply if I'm wrong. Just a suggestion :-)

Second Accessory	none
Keysense
Power Lock	BROWN / yellow	-
Notes: Found at a tan module near the hood release.
Power Unlock	white & brn/wht	-
Notes: Found at two tan modules near the hood release. The white wire will unlock the drivers door only, and the BROWN / white will unlock the other doors. use both wires and diode isolate each.

The car has power door locks but no remote. Also does anybody know what type of door locks this car uses?

The Mazda has a (-) trigger door lock system.

Yep, it is a negative single wire resistor type of system. It requires chassis ground through a 1Kohm resistor on a YELLOW /GREEN wire to lock and full chassis ground to unlock. You can either hunt down a resistor or my company offers a module that has variable resistors built in for such a setup. The module is called a DLR-U. Hope this helps.

Alright I am a little confused. So the for the door locks am I just taping into one wire to lock and unlock?

Also when hooking the siren to the alarm would I need a relay or can the alarm provide power to the siren?

None of my notes tell me to add a resistor inline of the relay to a single wire system, but you never know. Here's what I have for the 626 : The white wire will unlock the drivers door only, and the BROWN / white will unlock the other doors. use both wires and diode isolate each. Find these wires and test to ensure the proper connection. As far as the siren goes, there will be enough current from the siren output to engage the siren without the use of a relay.

Thanks for all your help Jeff your info has been great in helping me understand this. As for hooking up the relay could you explain how to hook the wires up to which part of the relay?

No relay required, rather diode isolate the lock/unlock wires.

but wouldn't the brain of the alarm need a relay being that the current it outputs would not be enought to operate the door locks?

Hmmm....that's interesting. Jeff, I do see where directed lists the colors you show but the vehicle's schematic shows a single wire system for the doorlocks (however, I don't have the keyless entry/ security schematics). I believe that perhaps the negative pulse system is for vehicles with factory keyless entry/security (maybe). There's no definite proof of this in the bit info that I have but either that's the case or both scenarios would work. Oh, KB, you wouldn't need relays because you'll actually be activating the vehicle's doorlock relays. Also, if you will, keep an eye out for both types of doorlocking systems because the last one I did, I performed the single wire interface. If there is a negative pulse interface, it would be good to keep in mind for future installs. You can't have too many options :)

Hey Mike, that's what I thought too about the vehicle having or not having the OEM RKE/Security system.I guess KB will find out when he starts to work on the vehicle.

Well, i recently did a 99 626 and the DEI info was right on the money. White, Brn/white and Brn / YELLOW. (-) trigger, no relays required. I wired it for driver door priority, since it's such a no brainer (if your alarm is capable) The wires are located in the driver kickpanel, just above the top edge of the panel itself.

So you hooked up the unlock to both the white and BROWN / 'white wires using diodes?
