Hi,
I am having trouble trying to change out my 2010 cx-7 headlight to a LED. The LED requires a positive and negative attachment and I could not find anything online that would help me know which wire was correct. I think the blue/striped one would mean that it is positive because I saw a wring guide for a 2010 stereo and it seems like the striped ones mean its positive?

I attached an image below to help visualize this. Looking at the two blue wires, one of them has a black/grey line across it and the other one is a full blue color. the left wire would have the striped one and the right does not

thank you for your help!
