Why any truck manufacturer would't pre-wire for a brake controller and trailer I don't know. Ford and Chevy do. You just have to buy the plugs/adapters for the ends, I mean "tow package". 
If you don't feel comfortable doing this wiring, take it to a shop. |
It's not likely to be prewired for brakes because it's already prewired for lights only. What are the chances that Toyota went through the process of running all the wires for brakes and lights, then only wired the lights to a 4-pin connector? Not likely, especially since the Tacoma is the smallest truck they make and has only a 6500 lb towing capacity. Most people that would tow with a Tacoma aren't going to be towing things larger than jetskis or a small Uhaul trailer... stuff that you don't need trailer brakes for.
Even the "small" 1500 Chevy and F-150 Ford trucks tow more like 10,000 lbs and come with a tow option that includes the 7-pin connectors, which is why they're pre-wired for lights and brakes.
