Where is the best place to get 12V for my canopy interior and 3rd Brake light?

 

Plug where you hook up a trailer. That could one place.

 

My first thought also, but that is part of the turn signals. So... the 3rd brake light flashes with the signal. Lame looking

 

For a 3rd brake light there is a wire in the back around your spare tire. It is taped off and has a green tag on it. That is for a canopy 3rd brake light. For power for interior light you could take power and ground from your LR park light. Then use a switch on the interior light but you will have to have your park lights on to turn on the light in your canopy, but if it is dark out your park lights will be on anyway right? The wire colours should be brown for power and black for ground.
Also a good idea is to hook it up with a 4way trailer plug or some kind of connector so if you take off your canopy for something you just unplug it instead of cutting wires.

 

Thanks, That was the info I needed!!!!!!!
