Electrical problems(?)

Hi! I have a 2008 s211 220 cdi.

It's sold in sweden and it doesn't seem like it has an alarm unit. I can't trigger it in any way and i can't find the siren under the wheel arch plastic.
Anyways, i can't lock my trunk. And now it has started to do alot of wierd things.

If i lock it on the keyfob and wait for a couple of minutes (can take 5 or 45). It starts flashing the indicators, Exactly like when you lock it, it flashes 3 times and then goes dark for a couple of seconds then flashes 3 times again. It can take 5 seconds between or 30 minutes it depends.
While driving the lock accuator makes wierd noises, like it's trying to lock. And then the car thinks the trunk is open and lights up the rear interior lights. This goes away after a second or a couple of minutes.

The lock accuator is new, the "trunk control unit" is new, and all electrical wires is taken from a working scrap car.

Has anyone ever experienced any of these symptoms? All help is very appreciated its driving me crazy,

Regards.
