Was meant to say: all my lights are working when i last checked. Also screenwash is working aswell as wipers. Radio is working. Windows go up and down.

Hi, my Evo has the same loose plug on it too. I think the orange thing is a blanking end and I feel like it might have been for a washer fluid level sensor but I'm not really sure?
