Ah, cool, I see.

Anyone know if the tuner sends raw resistor values to the player or if it sends pre-validated codes to the player?

Because if what this gentleman is saying is true, and if we can program Hijack the way I'm hoping that we can, then I can get my friend Tod's steering wheel controls working without an adapter box. All I need to know is where to tap into the factory wire (as described in the above message).
