Rearview mirror pos and neg wires?

Anyone know if the green wire all the way to the left is the positive 12v and the white and black one right next to it is the negative wire on a 2010 Tacoma? Thanks

Thanks, yeah I looked at that one before. The green is the 12v so I just need to make sure the white/black one next to it is neg. Doesn't mention it in that post. There is another black wire in there so I'm not sure which one is neg.

 

Ahh, I see. Check it with a multimeter?

 

Well I'm embarrassed to admit I have one but have never needed to or learned how to use one. I'm sure it's easy just never done it. Guess I could google it
