Friends,
I need some help. Bought a new 2009 S2000 Euro version, I believe an modified AP1 with factory alarm. All diagrams I saw include only a factory alarm disarm, not an arm wire!! Iam going to hook up de Viper 5902 HD. For possible problems with the doorlocks I already ordered the DEI 451.
But what about the arm disarm function of the factory alarm?? Is it possible to use the Viper and the factory alarm both?? Control the Viper with the OEM remote?? Or do I just have to wait 30 sec or both alarms when leaving the car?? Can't figure out if just lusing the doorlocks will arm the factory alarm (Yes, the car has to be collected still... ). Anybody some wiring of the factory alarm??
Last but not least, the factory led is 12 V, I beleive I can hook up the negative wire to the negative when armed wire of the viper, is it??
Any help would be great,
Joost from Holland, WK ready.

the door locks are negative triggers, you wont be needing the 451m relay pack.
the factory arm will also REARM if you pulse the lock wire.

Thanx for the doorlock advice, just to late ordered fur sure the 451 
So the Arm/ Disarm function of the factory alarm is the Lock unlock function. But will the Viper disarm when I use the factory remote??

factory arm - lock wire
factory disarm - disarm wire on car (refer to your wire diagram)
the viper will NOT disarm if you use the original remotes. the viper will have rhe ability to do whatever the original remote had.
the only unit i have dealt with and know you can disarm it via the factory fob is compustar. ------------- Ted

check the output of the viper unit. if it is 12v then you are ok.
if not, just replace the led with the new, brighter one ------------- Ted

Fortunally not possible, is an ingauge led for the OEM alarm.
Just finished my internet search, did cancel the Viper module, orderered a 6000 Compustar brain. This will operate and controle the factory alarm and
otherwise, so no LED problem and the factory remotes will still work. No hoping the Drone application will be somehow avaliable in Europe....
Also for me easy to install.....

I gotta ask because I can't figure it out myself. What's the point of installing an alarm in a car that has a factory alarm? I don't see the logic--add alarm to alarm.  Adding remote start I totally get though.

aftermarket alarms have extra features such as igniton or starter kill. A louder tone from the sire (grabs more attention) the range is significantly increased over factory stuff, and you get a shock sensor which can detect impact.
factory alarms only watch doors and sometimes trunk, but with aftermarket it will do all of that and like i mentioned dtect if a window was smashed or and force is put on the car. Many addition sensors can be added such as proximity sensors, glass bread sensors, tilt sensors (if you dont want it towed), etc.

Yes, yes, and yes all valid reasons to use an aftermarket alarm over factory but why use both? Does the math actually add up that two alarms protect and deter 2x better than just one? If so I think maybe it's time to add another DEI alarm/remote start to the one I already have. Would my remote start be twice as good?

Or do what I do on some Hondas, pull the plug on the factory alarm! Also Toyotas. As for new cars, just add a CAN alarm.

For me it's more easy if the factory installed alarm still will be there, so I can use the FOB remote also. But need some prox radar warning etc. Just adding an extra alarm will give me this opportunities, I can alwys remove the OEM alarm if neccessary.
It's not a CAN bus system, easy old wiring.
And also, if I use the OEM alarm this can control the indash 12V alarm led!
