Locating service connector for camper trailer

Hey there,
I'm Richard; and I have a 2013 Tundra Platinum. Recently I bought a pull-behind camper trailer. Everyone has told me that I need a trailer brake controller and that's it's easy to install. Haven't bought it yet because there are multiple possibilities of wiring harnesses; depending on the plug configuration. So I removed the driver's side kick plate and there are no available connector plugs in view. I've pulled on wire bundles and contorted myself to see everywhere and I cannot find the service connector. I called Toyota with my VIN and they said by all that they see, it was made with a tow package; so it should be there. Has anyone figured this out?

 

OOOH, Found it! It's a 5-pin connector 51362 wiring harness. Thanks to the installer who posted the wire colors a while back!

 

Be happy you've got an older Tundra. They quit making PnP harnesses post-2016 or 2017.

 

I'm pretty sure she's the last vehicle I will ever need.
