door lock wire color on 2009 mazda5

It's also about knowing the vehicle, against Ted's advice, I have no problems doing this on late Toyotas and some Hondas, if doing the domelight works for you fine. It certainly DOESN'T work on MkI Focus but does on the MkII (we've had 2.5 distinct Focus shapes in Europe, you've had one). You might have taught us something here.

So far it works perfectly. The trigger is instant, no delays that Ive noticed. Too soon to tell about false alarms though. The guy got his info from DEI directly, he spoke with them on the phone and that's what they told him. I'm not using the domelight supervision feature on the alarm since the car does it on its own when unlocked, maybe that has something to do with it? Howie, like I said, everything I do involves something new that people didn't know before. I just wish I wasn't always the test dummy! Oh and we now have the 2nd Focus here currently, not the RS of course, you guys get all the good stuff. Now for some general alarm questions: 1. When it passively locks, I don't get notification on the remote that it locked, is this normal? 2. If a zone is open, the remote wont tell me which one, is this normal? 3. When I turn off the ignition, it begins the arming sequence even if I dont open the door, is that normal? and is this probably because of the Domelight door pin hookup? I think I just answered my own question though......

as howie suggested, it works great for most vehicles, and select models from certain makes. I prefer using door triggers, but every installer is different, and there is no right or wrong. Simply preference.Ted

General rule,if it has domelight supervision initially, don't bother. This thing about domelights, try it on an initial model Focus (talking about the UK models here), 1998-2005, the dome lights stayed on for 1 minute ex factory AFTER locking and you HAD to go to the door triggers. Toyotas as an example, here the dome light dumps immediately the vehicle locks and thus I've always gone to the dome light. Never a false alarm. Now normally, especially on DEI, it takes 10 seconds after arming for the door triggers to come on line, known as settle time. If your dome light extinguishes in less than 10 seconds after lock and arm, you're O.K. 05 On, with the Focus we went to the dome light BUT we had to diode the 12v+ feed, that might be your only problem. Is the Mazda 3 or 5 the Focus?

It is a 5. So I might need to diode the trigger and then it won't start arming without opening the door?

No the diode is only to prevent false alarms when the doors lock and you get a spike when the light shuts down.

Ok how about my first 2 questions?

OK, one comment. I never ever use passive lock and arm, stupid and IMO dangerous. So without the experience I can't answer the question. Except I can guess. It's because you've gone to the domelight which goes through a processor rather than directly from a door pin, it's giving the alarm the wrong info.

I guess I'm stupid and dangerous then. I cant even begin to tell you how many times, with this car, Ive gotten in my home and said to myself, is the car locked? Then I venture back out with my remote held to my head until I'm practically next to it anyway because the factory range is pathetic. I've had passive arm and lock on all my cars since 1993 and locked myself out the second week after installing it. It has not happened since. Some people shouldn't have passive locking. I like to walk away from my cars, with my keys, and not worry about leaving it open all night. It looks like the spring project will be to remove the domelight trigger and find the door pins. I dont like that it will set when I haven't gotten out of the car. I like it even less the remote wont confirm it. I'll have more patience then so its ok for now. One last question, whats the deal with the techtip you linked me to and this diagram I found on another site? This one is for my car but is using a - trigger. The DEI one uses a +. How can they both work? Why is this happening to me?! lol Youre all being very patient and helpful with me, I appreciate that more than you can imagine. Without the guidance I got here, I couldn't have done any of this and for that I'm grateful!

Not you I make my customers sign waivers if they wan't it. I earned lots of money in the 80s doing call-outs to rescue fools who had locked themselves out of their vehicles, armed with my special universal key, a.k.a. a hammer, hence the waivers. Only seen the DEI tech tip, not properly looked but I imagine it's the way they set up their diodes hence the polarity difference, doesn't matter, just use the pos trigger wire.
