Car won't start.

[taks]

hey guys,
got a problem with the car so need your help.

after taking out the harness connected to the aftermarket headunit , the car won't start nor the headunit, but everything else works. (headlights, aircon etc.)

when i pulled out the harness there was another harness (blue) that was connected to the same line? don't know if it was plugged into anything or maybe have been disconnected when i pulled out the harness from the headunit.

any help would be appreciated.

car is facelift EK
