I have just installed the DD in my 04 G Coupe, i used the Metra, and the 7550 harness to connect it to the 225w Bose amp.
But my DD player has steering wheel control, but i dont know how to wire it, since i dont have a wiringdiagram for my G.
Anyone that can supply me?

 

I've never heard of a DD unit having steering wheel controls that can be integrated directly with stock ones. What unit is it?

PAC makes a universal adapter for our cars that works with DD units that have a remote control. That's what I'm using.

 

I have this DD player http://www.autodvdgps.com/index.php?...roducts_id=165

But i need the wiring diagram for the 04 G35 Coupe 6MT find out how to connect

 

you need an interface module... the wire itself is so that you can control the deck since I don't know who your manufacturer is I can't tell you which one to buy. there's about 4 wires you have to hook up with a variety of resistors that control the volume and the track up/down buttons.
if that deck came with a remote you can use the regular PESWI-X but if you don't you may have some issues.
