2004 Silverado Bose Harness Diagram/ipod/aux Converter Help!

[davo32683]

Hey guys, just picked up an Axxess AIP-GM01-ID iPod/AUX input converter for my truck from Circuit City. Seems fairly straight forward to install, but I need to know what needs to be done with the red (power) and black (ground) wires which I would assume provide the charge for the iPod while connected.

 

I was planning on tapping into the large factory harness, but I don't know which wire is which.

 

Is it safe to connect the wires to the constant (+) orange wire and ground black/white wire? Or would I need to hook the power up to say the accessory/ignition wire in the radio harness? Don't want to drain the battery or anything!

 

I would appreciate it if any of you stereo gurus could help me out so I can have a simple install tomorrow morning!

If your just looking for a ground and a switched power I would stay away from the radio harness. Is this going into any other part of that harness?

[davo32683]

Naw, I'm supposed to unplug the small harness and plug this one in. I believe it's the 12-pin one. The wires supplied are very short and it would just be very convenient to tap into the harness.

See the kit didn't come with any kind of instructions or anything, it's straight forward except for those two wires.

I don't do any aftermarket stuff but the problem with this is that there isn't really a ignition feed to the radio. There is a B+ that keeps alive the memory like there has been forever. There used to be a wire that was controlled by the ignition switch that powered the radio on. Not so anymore, the radio is essentially a computer that is told by another computer its ok to turn on. As a tech we do not deal with how to fool that circuit and most agree it's not a good idea to try. I would try to pull that switched power from elsewhere.

So I can't even pull it from the orange constant wire? How about the ground?

[minibike132]

You could pull from the B+ or constant wire but I have no idea what kind of amperage your device will draw. If you want a ground terminal A-12 which is black with a white tracer is one of the grounds.

If you want an educated guess....if this is something you drive daily and you are only going to leave the plug without the i-pod plugged in, then you will not draw enough on the B+ to kill the battery. If it sits for a couple of days though, without knowing the device draw I can't tell you that you will not kill your battery.

It's up to you. There is no switched power. The full time power is terminal B-1 it is the orange wire. Good luck and let us know how it goes.

Thanks sparkstech. I'll call Axxess/Metra tomorrow and see what else I can dig up about what this unit before I do anything.
