Trailer Wiring harness

Just got a 2018 TRD Sport and it has the trailer wiring set up in the rear bumper. The old utility trailer I have had for years needs to have the wiring replaced and before I buy a new 4 pin harness I want to be sure it will work in the TRD setup. I know from having boats that all connectors are not the same. Some are hard plastic and others are soft and pliable. Any recommendations?
Thanks
Russ

 

There is a trailer pin wiring standard... if in doubt, meter the pins:



Also, check eTrailer.com for all your towing needs:

Thank you for the reply and diagram but I was looking more for a brand name of a harness that will fit the Tacoma without having to "shave" or force it to fit into the receptacle on the bumper. I have looked at Reese and Curt. Anyone used either of those?
