Okay, little update from here.
Lock`s are still dead, i have a new receiver and two new transmitters. And i also have new problem.
Pictures will tell.
The instrument cluster should look like this.
And my instrument cluster looks like this.
So im missing that black plug with six pins where i should connect my receiver.
Does anyone has any idea where i might get one or do i just have to hunt down used cluster and replace it compeletely? The plug connects in those two holes. Actually there is a third one also but it doesn`t show in the last foto. This truck drives me crazy before these locks are working.
