Okay - in the process of installing my DD and I'm highly confused.

My metra 70-7551 harness didn't come with a wiring diagram so this is the majority of my problem.

I've got power to the HU but I have no sound at all. The only wires I don't have hooked up from the metra harness are:

Blue/White
Black/White

Does the blue/white go to an amp switch? And the black/white to a ground?

 

Blue/white is probably the amp signal wire - a few of the equivalents to the 70-7551 it's the antenna amp signal wire.
Black/white is the amp ground, ground it with the rest of the stuff.

 

Hmm...ended up connecting the blue/white to an ignition wire and finally got sound.

I didn't connect the black/white to anything, though.

 

I have a Pioneer p-3200bt, JDM DD, Metra 70-7551, antenna adapter all going in to my 03.5 sedan with bose. Everything is out and ready to hook up but am still confused about the bose amp. Do I need to do some splicing or hould every thing just hook up? Help.....

 

Here is a pic of the wiring diagram. I did a simple google search. Please ignore the handwritten parts.



The harness just plugs into the factory plugs and you connect the colored wires (red, black, blue, yellow, etc..) to the aftermarket stereo.

 

The only wiring outside of the diagram pictured above is that with the 3200, both the Power antenna and amp turn on connect to the same wire from your headunit. Also, the amp ground and the black chassis ground wires BOTH connect to the black ground wire coming from the 3200. Then all 3 wires get connected to a solid chassis ground together. See my video here:


If you have a PAC SWI-PS to connect, that will require additional soldering and splicing as well.

 

Nice video! Hope mine goes that easy also.
