Installing a Brake Controller on a 2011 Volvo XC90

Question:

Anybody know how to get my wires through the firewall on a 2011 Volvo XC90? Where is there a path? Pictures?

The best path is usually via a grommet up under your dash on your 2011 Volvo XC90. You may find it easier to remove that grommet by starting under the hood. If there isn't a grommet available you will need to drill a small hole. But be very careful not to drill through anything on the other side.

I included a video for you to look at (see 4:50 mark)
