problem with alarm, 1987 volvo 740

Now its looks like i've found the real name of my alarm. Thor TH446.

Which doesn't mean a thing, once more do you have a wiring schematic?

For the car? Well i take a pics on the wiring diagram to the alarm. But i dont think you see something. I write down whats color and where that go. Wires from 12pins contact Orange    LOCK White     LOCK Yellow    LOCK ORANGE / Black             UNLOCK WHITE/ Black              UNLOCK Yellow/Blck              UNLOCK Black     GROUND I've found that RED / Black OPEN TRUNK Red       12v I've found this to Pink      Siren Brown     Turnsignals Brown     -| |- 2 pins contact For the led light 7 pins contact Yellow    TO THE RELAY - But to witch contact i dont know Blue/BlackWINDOW CLOSER Orange    Break Blue      Door switch White     IGNITION Second 2 OVERIDE SWITCH 4 pins contact To shock sensor The relay has this cables ; White Green Green Yellow But where could i put this?!

No good at all, those lock and unlock wires should be marked as common, NO and NC. RED / Black trunk open is irrelevant to your car. Blue door switch, this also needs to be connected to trunk and hood switches via diodes, that's assuming these switches still work after 24 years. You will have to provide a hood switch. I have to know what those colours are on the relay, it's a starter cut. I'm guessing white goes to 86 and joins to your ignition white. Yellow to 85. Cut starter wire, key side to green at 87a, starter side to green at 30. Needs a 1N4004 diode (unless already provided) between 86 and 85 with the band to 85. The problem is from your questions, your knowledge and maybe skill levels are not enough to achieve this.

Yes the door cables are markt with that. So how i connect the door cables? I have electrical open to my trunk.

Then you will need another relay and diode for the trunk release unless your switch is negative powering a relay. Can you at least tell me which of the lock wires is which?
