To use the Curt Spectrum Trailer Brake Controller # C51170 on your 2015 Toyota Tacoma, you will want the Curt Custom Wiring Adapter # C51362. It sounds like you may have a pigtail harness like # 3040-S with exposed wires on one end and this adapter plug for under your dash on the other. If that is the case you may use that, but you will need to then use butt connectors and cut the quick connect end of your brake controller.

I've attached a couple videos to assist.
