opel corsa d alarm

Hi I am reading this forum for years and it is very helpful.So I have an Opel Corsa D and I have installed a viper 5902 alarm system.Everything is working perfect except door locks.I have connected the lock and unlock to the central locking button wire, witch locks and unlocks with (-) ground.The issue is that when I arm the alarm the car locks, but when I rearm the car unlocks.It was obvious with this connection but I want to fix it.Does anyone know the wires for lock and unlock?
If anyone here want's the wires for corsa D OPC let me know to post it.Thanks

Simple, it sounds like a 1 wire system, simply don't re-arm!

Sorry, I didn't explain that too well, it's sequential, i.e. hit the wire once, it locks, hit the same wire again it unlocks. Somewhere are the lock motor wire outputs, probably one of the fuse/relay boxes, but be careful, I've done the late Astras and that method does the doors but not the hatch.

I have done me too astra and I have used canbus module for lock/unlock.
I tryed to find these wires from fuse box but I didn't found them.Have you install alarm on a corsa?What did you used for lock/unlock?And for astra what wire did you used?Thanks

This is not a solution because if you want to be sure that the car is locked and armed , and you arm the car again the doors will unlocked..
Do you know if this diagram will work with my car? Single Pulse to Lock and Unlock https://www.the12volt.com/doorlocks/page4.asp

You are absolutely correct, I've been away and I read your last post and thought "latching relay from armed output to open-circuit (break) unlock wire" Honestly! Got to be cheaper than a CAN adaptor.
Ref the Astra, there's a second fusebox/control module left side rear, lock/unlock motor wires BUT it only does the doors not the hatch!
Bloody Opel/Vauxhalls are becoming a PITA, overcomplicated electrics!
Pre- 2005 was sooo easy.

I know that my friend..I have installed very easy on other cars but this was a trouble..On astra to connect all the the 6 flash lights I had to connect 6 different wires to them with diodes because the astra has two fuse boxes..The next astra that came to me to install an alarm I used canbus module..

Can't agree more. By my third Astra I was so sick of getting at those damned front indicators, so I used a Cobra CAN alarm. Fine after I threw away their terrible instructions!
I now use DEI units and they work fine.
As far as I'm concerned ANY German car after 05 has to be done with a CAN alarm.

Yes I use DEI all the time...But the only thing is that in corsa I have done remote start/turbo timer/trunk release/open lights/close windows and all the other connections that I need and the only issue is the door locks.It's not worth to install a can system.Also DEI has not released yet the firmware for canmax400.
Whatever I will try the way with the relays and I will post the solution.Thanks again!

And I don't think you will see it. GM started to sell the Astra as a Saturn in the US but of course that's fallen through so unless they continue it (unlikely) you will never see one for Opel/Vauxhall.
Even the VW version has problems on European made cars.

Directed has created a company on Europe that develops firmwares for European car's. Firmware is available for Opel Astra H/J , Insignia and for most opel car's except Corsa.You can see it on XpressKit.com

Thanks for your last post do you have any contact info on this company?
They won't even sell the 5900 series in the UK yet, though they've let me play with one.

You can see and download the firmware from here: xpresskit.com
