You'll need a premium wiring harness and a 1.5k ohm resistor wired to your remote wire.

resistor part#: Radioshack 271-1120

wiring harness part#: Scosche FDK11B or Metra 70-5522

Is there instruction to go along with this and is this something best buy may carry? and whats the smaller plug? I dont see a clip in my car that it would plug into

The smaller plug has the RCA leads on it that will plug into the aftermarket radio. I'm not sure if Best Buy would have it or not.
