Hey iv been having other issues with my acadia. I'm hoping someone may know what these wires are for. The look like at on point the clipped in by the break fluid resivoir. They have been cut at one point and just curious to what they do. And I also have a wire that comes from the alternator to the pcm up front. Any ideas what that may be for as well. Thanks for any advice.

What issues are you referring to here?

I ask because the issues may not be related to the wires.
