I have an 08 Tacoma double cab 4x4 and an 2010 Tundra 4x4. I want to purchase an enclosed trailer to use for work. 16 or 18 foot. The Tundra came ready to tow, the Tacoma did not. I put a class 5 hitch on the Tacoma and one of those plug and play harness adapters, 4 pin. I use it to occasionally tow a bass boat. My question is regarding the typical wiring on enclosed trailers, will my 4 pin connector be enough (I assume it does lights only). Do these kinds of trailers usually have electric brakes etc. I'm not sure what is required to make my Tacoma tow the trailer. The Tundra will be fine.
