Brake controller wiring

I'm looking to hook up my Tekonsha P3 brake controller but can't find any write ups for the wiring. I appreciate any help. A link would be great! Thanks.

 

you can get a wiring pigtail from Tekonsha / with instructions, and it plugs right into the truck.

 

Does our truck with the tow package have an actual plug? I was under the impression that there were loose wires but no plug.

 

Your trd off road has the plug. Mine was tucked up under the dash completely concealed by electrical tape. Took a good minute to find it.

This is where I put mine.

 

I believe 2012 even came with the the pigtail to plug in, only had to wire it to brake controller harness. I think there is a good YouTube video showing you how to.

 

Any idea of where the wires go in the harness? My 08 has the under dash pigtail but no relays in the towing spot and no factory trailer plug
