Aux Install Help

**OriginalName** · 08-02-2012

Hey guys, new here and have a question that hopefully someone can help with. Basically me and a buddy tried to install an Aux input for my 2004 Grand Prix. The one I got was the PAC AAI-GM12 model. Anyways long story short we hooked everything up and it didn't work. We figured that the wire we connect the power to was wrong so we tried a couple until finding what we think was the right one (the orange wire). Still didn't work. We just couldn't get the AUX to come up, using the BAND button or the CD/AUX one.

Has anyone used this with success? If so could you give me a little step by step on what you did? I have the Monsoon 6-disc changer.

Here's the instructions for the PAC thing

Here's a couple (bad) pictures of everything hooked up.

and here's the part used...

im no expert, but this may be the problem.

Requirements: 2003-2006 SUV’s and trucks with a RDS or Navigation radio. The SUV or
truck must have a factory XM receiver, factory DVD Rear Seat Entertainment (RSE) or
factory/aftermarket CD changer (factory 6 disc changer built in the radio does not qualify).

What did you use for the switched 12v? You need to go to the glove box and look for the sunroof fuse. That one is switched. You wont find a switched 12v behind the radio.

You know what, we actually hooked it up to the radio 12v.

there is no radio 12v on a 2004 GP

Hmm, well I had found this list and the Orange made the most sense.

Radio 12v orange + radio harness
Radio Ground black/white - radio harness
Radio Ignition (Class 2 Serial Data)
Radio Illumination gray (dimmer) + radio harness
Factory Amp Turn-on same as power antenna wire
Power Antenna purple + radio harness
LF Speaker +/- tan - gray +,- radio harness or amplifier
Notes: The amplifier is under the rear deck.
RF Speaker +/- lt. green - dk. green +,- radio harness or amplifier
LR Speaker +/- brown - yellow +,- radio harness or amplifier
RR Speaker +/- dk. blue - lt. blue +,- radio harness or amplifier

I think the orange is actually 5v. Plus, that is constant. You need switched 12v.

So I would need to somehow connect the red power wire that comes with it to the sunroof? That makes sense, I wouldn't know where to start to make that happen though since the wire is pretty short.

**KeithGTP03** · 08-02-2012

Go to Autozone or Walmart or anywhere really, and get a roll of primary wire. Get an add-a-circuit and plug that into your sunroof fuse in the glove box.
Add a circuit:
Cooper Bussmann/ATM fuse tap converts one into two fusible circuits - 10 Amps maximum on added circuit (BP-HHH-RP) | | AutoZone.com

I will have to try that. Is there a way to run the wire behind where the head unit is to the glove box?

Another question as well. Even with/without power going to it the Aux option won't show up on my stereo. Shouldn't that show up regardless of having a switched or constant wire?

**KeithGTP03** · 08-02-2012

It wont if that orange wire you tapped into is 5v. The aux unit is 12v. They usually have a tolerance from 9v to 17v. 5v is not enough to turn it on, and the radio needs to "see" it in order to switch to aux.

**KeithGTP03** · 08-02-2012

And yes, to run the wire...just drop it down, behind the radio, to the passenger side and run it over to the fuse box.

**OriginalName** · 08-02-2012

Alright man, will definitely try that out and see what happens. I've seen a couple other people that mentioned using the sunroof to get it to work so hopefully that does the trick. Thanks for the help.

Just for knowledge purposes, do you know what that blue connector does at the bottom of the head unit in the picture? We unplugged that just to see what would happen and everything on the radio still worked perfectly fine.

**KeithGTP03** · 08-02-2012

Did you check if your CD changer or steering wheel controls worked after unplugging it?

Didn't even think of that. Though I wouldn't think that's it because the AUX device has a connector that you put in there and from what I hear the steering wheel controls should still work for the radio/cd just not the new aux input.

It may be for factory XM/Sirius. I never got a chance to work on an 04+ prix when I was in the business.

As far as I know mine didn't come with XM. Would the wiring still be there regardless?

**KeithGTP03** · 08-02-2012

More then likely, apparently it was easier for them to use the same harnesses throughout rather than using different harnesses. And that way, a customer could add on XM/Sirius a lot easier if their car did not come with it.
