Help with identifying this wire?

[jerrychen0067]

Hi, guys, I bought a saab 93 strut brace, which is the only thing I can get in Taiwan, and to install the bar this wire gets into the way.
I wish to unclip this wire and push it down so I can clear the strut brace.

I have no clue what is this wire and how do I unclip it and will this influence anything??

Thank you for your help.
