Rondog, I am having continual fails in trying to post a photo of the cable. But it comes out from the bottom of the fuse box. He tapped into it - did not actually cut the covering, just was able to pierce it so a small hole. Should be no doubt about which red cable, it is the only one.

 

OK Appreciate your attempt. Hope I never need it!!

 

Valerie - a picture would be difficult but it is located behind the right side wheel well. Need to remove an underneath panel to access it (he did not think that the wheel well liner needed to be removed) which is why no picture. He indicated it is clear what box is the one, only one on the red battery cable in that area. Sorry, best I can do.
