Can i use the black/white wire as a ground?

 

i cannot find the fuse INT LTS...

 

UPDATE 4/19 Everything installed and worked. Used Orange for + and Black for -.

 

You never provided the year/engine/etc of your Vue, so I was using the 2006 wiring diagrams. Please tell me what year your car is, and I will try to provide an answer based upon the correct wiring diagram. I do not own a Vue.

 

already finished the job

 

Kindly provide the year and trim level as requested.
It may help the next person that comes along

 

This was done on a 2008 Saturn Vue XE, the weak 4 cylinder. I was missing the passenger side mirror and the originals didnt have lights. The process was almost the same as the youtube video i posted. Yes i bought a pair that werent the same color as the interior.
