Trying to install my Turbo timer and having problems undoing the ignition case. They use a strange screw never seen before. Is this where the harness plugs in what kind of driver can I undo these with. Checked round the ECU doesn't look like I can plug it in round there.

 

Thanks guys sorted it anyway now....Used a small torx driver and that got it open. Harness was wrong though needed 2 next to 2 but had 2 above 2
