My '01 M Coupe had both the alarm harness and the siren connector, both of which I cut off and properly soldered my own wiring. I can't imagine that it would be totally different and that they had changed the colors. The siren connector was deep in there and a little bit hard to find, but I found it after a couple minutes and a good flashlight.
I'm not using a wiring harness for the alarm, so I couldn't tell you if it'll match the harness that I'm assuming he bought from Autotoys. But I can tell you that all the colors on the Book of UNGO site matched my car's wiring perfectly. I hate to ask the obvious, but did he grab the right harness? There was only one under there that wasn't being used, so I don't know what else he could have grabbed, but it should be a twelve pin harness (mine only had ten wires though; one was already listed as "unused" and the other was for the rear doors, which are obviously not used).
Jon, where did you mount the Passport? I tapped the sunroof switch for my V1 and found that the colors up there were different from the rest of the car.
The 3.0i is completely different than the M cars. It already has keyless standard from the factory. The "main alarm connector" is not behind the glovebox. I have not seen what is there in real life, only over the phone and in digital pics in discussions with Andy.
I got Passport power from the switched power that runs the alarm behind the glovebox. I corrected the wiring on the sunroof switch so it lights up per Ron's instructions.
I don't think I can link to Imagestation pic, but here is 3.0i wiring:
I have NOT taken apart the dash yet to look for the 12 pin connector, and thanks to JonM's post (thank you very much for the pic and useful info Jon) it looks like I don't need to go through the aggrivation...I tend to think that even if I find the alarm harness, the 3.0 wiring harness may be different than the earlier models. Bavarian Autosport has a 3rd party alarm that plugs into the factory connector, but is only available for earlier Z3's. Now why would a 3rd party alarm for the older Z3's not work with the 3.0 harness unless the harness itself has changed (either the connector itself, the pinout, or both)? I confirmed with Bavarian that the 3rd party alarm they have will NOT work with the 3.0. I'm thinking even if I find it, assuming the connector is even the same, I'd need to check the pinouts before even attempting an install. The problem now becomes not only where to look, and what does it even look like?
The other part of this puzzle is the OEM alarm. The OEM alarm MUST be dealer installed. Bav. auto. explained to me that there is some "coding" that must be done in order to be installed. What this "coding" is I don't know.
It may be that since the factory alarm arm/disarm is integrated into the keyless entry on the key, that this is the source of needing the "coding"? That's all purely conjecture on my part, though. :dunno:
Even more basic quesion I suppose to ask is will ANY aftermarket alarm work with the 3.0's pre-wiring harness because of this need for "coding"? Having no idea what this coding is for or how it's used in the alarm, again ... :dunno: Bavarian rep. said that there was no aftermarket alarm that he knew of that directly fit the harness on later cars.
My GF has a Z3 3.0 with a late '01 build date. Notice in the Accessories catalog, the alarm for this car is different from earlier ones. Its also alot cheaper. My theory is that much of the alarm kit is already installed on the newer cars. Anyway, it seems true that you must buy the alarm from a dealer, and it must be installed by a dealer because of some software programming. For a long time, the software was unavailable. It has only recently become available (see my letter in the newest Roundel). I've heard that panic mode still doesn't work.
I even tried to order the alarm from Circle BMW. They wouldn't sell it to me because they said it required dealer installation and programming. Why I couldn't buy the part for cheap and then bring it a local dealer, I'll never know.
So why the new alarm? I don't know, but my WAG is that the integrated key and rear-view-mirror receiver on the new Z3 3.0's seems to come part and parcel with a new alarm system that is different from previous ones.
I don't know how helpful this info is, but at least you know either that (1) they're not blowing bubbles up your butt or (2) if they are, they're at least keeping their story straight because you're not the only one getting that story.
I had a BMW alarm installed on my '00 Z3 Roadster, and it came with a key-fob alarm controller. My '01 Z3 Coupe has keyless entry... the button for this AND the alarm are already on the key-grip itself.
I'm thinking the BMW just installs a very simple module and the encoding they do is to match it up to your existing keys. But I could be wrong.
