Do I need a trailer break on my 2013 Tacoma, If so where is my plug?

I cant seem to locate the plug in for the Reese and pigtail I bought. Is there any way to find some pictures. I have spent an hour upside down underneath and looking. Am I looking for something that doesn't exist? It is a six cyl. TRD package 4 door. I am towing a 5000lbs camper/icehouse.
Thank you for any help.
PS anyone know a good chiropractor?

 

I don't have any pictures, but the plug is up high in the driver's foot well. Remove the side kick panel above the foot rest and it's tucked away really good. It's a white plug. I really had to pull and pry things out that were loose and finally found it. Good luck!

It is a pain to get at-way up there and tucked under. Drivers side kick panel area. I never did find it (my Toyota parts guy did...)
