Hello, no you don't need a climate control knob kit. You do need is the wiring harness. This will allows your new head unit to send signal to the factory amp and then to the speakers. DO NOT try to run the bose speakers directly off your head unit. You'll burn it up.
Metra 70-7553 is the correct one you need. You also need the antenna adapter. Metra 40-NI12
