Stop Light Switch Wire Color On 2008 Toyota Highlander

Question:

Hi Guys Your video you sent to me is helping a great deal. Now Im to the point of connecting the red brake wire from the controller to the blue wire on the Highlander. I cant find the blue wire in the harness but there is a grey brake light wire at my 4 pin harness connection. Can I use this grey wire instead? Thanks again,

In order to hook up the red wire on a brake controller like the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 to a 2008 Toyota Highlander you will be using a blue/gray wire. If you use a circuit tester you can confirm this by checking for the wire that only has power when the pedal is depressed.
