Ok, so I have my 87 Turbo with TEMS. The thing is that it doesn't work, the lights on the gauge cluster don't light up either. Before I stripped out the interior and swapped stuff from my parts car I could press the Sport button and here the actuator motors moving, but after I swapped it doesn't do anything anymore. I tryed switching TEMS computers but that didn't seem to work. So I don't know, if someone could help me that would be awesome.
