If it has the factory 7-way trailer connector, your 4Runner will indeed be pre-wired at the factory for a brake controller. The Tekonsha Primus, part # TK90160 you'd looked at is an excellent brake controller that would work very well for you. You'll also need the # 3041-P brake controller wiring adapter, which would plug into the factory connector as shown in the installation video I've linked for you.
