Hi everyone, I'm Francesco and I'm new to the forum. I would like help with my ford sierra cosworth 2wd because the car has been abandoned for many years and I am now restoring it.
Can any of you tell me what this control unit (I attach photo) located under the dashboard on the passenger side is for? Where can I find an electrical connection diagram?
Currently the car has some electronic problems because the dashboard doesn't work but the lights inside do, the on-board computer doesn't work, the indicators don't work. Does that control unit have anything to do with these problems?
Thanks to anyone who can help me, sorry for my English but it's not the best.
