Disabling S5 Security system
Ok so I've learned its part of the S5 ECU, so disabling at that location is out of the question? I'm pretty handy with a soldering/desoldering irons, so if it were as easy as removing a component, not too bad.
Otherwise, is there a sensor (door lock cyl maybe) that can be tripped open, or cut closed to keep the security system from activating?
Thanks!

No, it is part of the CPU (body computer) not the ECU (engine/emissions computer)
The system only activates if you lock the door from inside the car, and hold the outside door handle while closing the door.
So if you don't want the system to arm, don't lock it from the inside.

I'm guessing that the sensor has the circuit copen when the handle is up, and its just not plugged in?
I have the alarm go off at random times... Like I'll walk away from the car come inside, and 5 minutes later the alarm is going off. I live in a pretty remote area of town, and there is *no one* around.
I just want to disable it all together, but ntohing seems to work...

UNplug the top plug from the CPU, and it'll be done. Ive had this on a couple of other s5 cars...the door lock sensors are pretty sensitive sometimes. IF it works okay, leave it alone, but when it gives you problems, it's best for reliability and such to just disable it.

some dreaded previous owner (DPO) installed an aftermarket alarm in my car (and not very well judging from the wiring and sensor mess) Do I have any recourse but taking it to an alarm professional? I had my locks and stuff go crazy with me IN the car once...freaky as the new alarm includes a screamer...

Ok guys, I unpluged the top most plug from the body cpu on the driverside kick panel. It didn't do too much.
The alarm system still activates. However, everythign seems like normal, until the alarm trips. The only difference now is that the horn doesn't work.
So I'm thinking that the top plug (or the one i plugged is for the horn, not alarm?)
Any Input?
Kevin, could you elaborate what plug it is? I knwo the top, but I thought that was the one I unplugged...
EDIT: and yes it did take a month do that one thing...

Perhaps I told you wrong, and there is another plug above the one I am familiar with. The one I am talking about has a lot of wires, probbaly 20 or more. Toward the top. UNplug that bad boy and see what happens. If I had a spare s5 cpu I'd take pics, but I dont. Perhaps I might check on the one in the 'vert if need be. Just unplug the other plug, I'm sure you'll figure it out. It isn't rocket science. I figured it out myself, by deducing that since s4's had a large alarm control box, the s5 had to have one somewhere. I then figured that they added it into the cpu, but didn't redesign the entire cpu circuitry for just that, so it was just an add on plug, I unplugged things until it killed the alarm.

Thanks Kevin, I remember there was a larger plug under the one I unplugged. the one I unplugged wa only 6-10 wires. I'll do that and post back in a few hours. Thanks!

2nd harness from the top, has about 20 wires. Disabled security system.
Thanks Kevin!

You better go check to see what no longer works... things like the horn, or ignition/door key lights, key buzzer warnings, lights on warnings, etc

^^ Horn was disabled when i unpluged the very top plug. It works fine when I re-plugged it back in. I haven't seen any bad side effects (other than the security system not activating) from remoing said harness. Does the FSM document what the wires are for?
Also, have blinkers, lights, dash lights, shift buzzer, washer fluid low light, all idiot lights per when key is in acc mode. Can't find what else it might disable...

oaky, here you go... this is a list of everything you loose doing this:
ignition key reminder
Ignition power to the CPU
12volts power to the CPU
door key lumination
seat belt and passive belt warning
head light warning
and with air bags you also loose flash to pass,
and of course a perfectly good security system

... You mean I get rid of that damn seat belt beeping too?
lol
Damn, I lose flash to pass though huh and head light warnings... :/
Raelly though, the "perfectly good" security system, was far from being perfectly good. Bad habbits of going off for "no reason" at the worst times (3am ish, or at work, ect.)
I wonder if there are certain wires that could be removed from the harness to disable only the security system...

What is the biggest weakness/problems with FC owners here and at Teamfc3s.org... they rather rip it out than fix the problem.
Mark's RX-7 rule #3 FIX THE PROBLEM, instead of ripping out what is reporting the problem
In therory, you could cut the input wires for the door sensors and you would never arm.

I didn't note anything at all (other than the alarm) lost when I did this, but the car wasn't a DD either, so I could have missed something.
Jeez, what's the big deal guys? We're not gutting out an entire interior or a/c here, we're unplugging a plug. IT is reversible if you don't like it, takes all of 20 seconds to complete.
