Stereo Gurus Question

Question for someone who knows there shit when it comes to stereo installations.
My aftermarket stereo has 3 wires for the SWC controls.

GROUND
KEY D-1
KEY D-2

Just need to know where to connect D-1 and D-2 ?

thanks

 

What kind of radio and model number?

 

Rosen Piranha

 

By there wiring diagram at best and I mean best.. ( I assume you have there nav. Radio?)

There diagrams are about useless.
If you have a model number that would help me better tho.


I'm going to assume you have the swc harness?


Online manuals sucks.

You do have a pac. For your steering wheel right?

 

I finally figured it out using the Axxess information. No Pac or Axxess harness was needed. Thanks though.
