way exactly do i need?

i have a 2011 tacoma dclb sport 4x4, and i am planning to put in my old head unit from my old truck. Do i need anything else besides a wiring harness, and a dash kit? Crutchfield has some steering wheel interface thing that i think i need but i am not sure. I am still wanting to use my steering wheel controls so that is why i am asking. and if anyone knows a better/cheaper place to buy what i need please let me know

 

PAC-SWI-PS for most stereo brands to the steering wheel control. It is not required to operate the stereo however. You can get it later down the road is you want.



Wiring harness and dash kit and you should be good to go, unless you have a JBL system.
