Trailer wiring harness

I have a new 2015 Tacoma with the SR package. It doesnt have a trailer hitch, and I intend to install one ASAP. I've done a few before, but don't really like adding any wiring that has to run under carpet or inside trim like some T connector kits I've done. They always get a pinched wire and short at some point whether weeks or years later. I was really expecting the Tacoma to have a connector ready to plug a harness into like my 2011 Silverado did. These really aren't ready for trailer wiring and require splices or Ts?

 

Most people I know adding harnesses afterwards use the plug and play T kit you mentioned, similar to this:

You can wrap it in wire loom to prevent pinching. Zip tie the loom to the existing wiring and/or frame and you're good to go.

 

I deal in trailers. With that said I see more trucks with failed factory trailer harnesses than I do with aftermarket installed harnesses.

Take your time and install a vehicle specific harness and you will have a harness better than factory.

What I'm saying is don't be afraid of aftermarket harnesses at all.
