I just want to know for sure, where can I find out the wiring for a 2006 Impreza's stereo? I want to make sure I will be plugging in my Pioneer and Omni-fi up correctly.

And yes I know the Antenna lead needs 12V power antenna going to it.

 

why not buy an install kit

 

theres tons out there!
i myself have an 06 impreza. i got mine off a local best buy store. really cheap and real worth it, unless u want to go ahead splice-n-cut ur wires.
crutchfield has them too.. almost all aftermarket audio shops.

try google
