Sounds like you are looking for a 7-way for a brake controller and a 12v hot lead for your 2008 Toyota Tacoma, so I would recommend the Universal Installation Kit for Trailer Brake Controller, part # ETBC7. This includes everything needed to install the wiring for the 7-way connector, once you have the 4-Way installed. I have included a couple of videos of part # ETBC7 for you to check out.

Although we offer many different brake controllers, I would recommend a proportional-type controller like the Tekonsha Prodigy P2, part # 90885. A proportional controller has an internal sensor that can detect how quickly and at what intensity the tow vehicle is braking, and will then send the appropriate amount of voltage to the trailer brakes so that both the vehicle and trailer stop at the same rate. This leads to a more efficient, safe and predictable braking action. I have included an install video of this brake controller on a 2012 Tacoma for you to check out. The model year is different but the install will be similar.
