Steering wheel audio control

[Chevysuburbanrider]

My bad i have a 2004 suburban and the aftermarket radio i have is a Smart Interact something cheap for now but it have its own wires to tap into the steering wheel control

Key 1 - which is Black and orange for steering wheel control

Key 2 - which is Brown for steering wheel control ( when vehicle have 2 positive signal wires)

P.CNTR - white & blue for amplifier signal input

Can RX - Yellow for can Bus Control cable

CanTX - Red for CanBus control cable

 

Need to know where to patch these wire into the factory connection

Thanks in advance if anyone know the color code to make this aftermarket system work
