2009 Aveo Hatchback Head Unit Wire Colors

[NxC]

just recently bought a 09 Aveo hatchback. Now my problem is that the previous owner had an after market head unit installed but instead of getting an adapter for the harness, he had it hardwired in. He took the head unit out before selling it to me and gave me the factory one, telling me to just plug it back in. Like an idiot I didn't check so I have to wire it myself.

The factory harness for the radio is missing all the pins so I can't cross reference the colors. While I do plan to purchase a reverse harness for the radio, I am at a loss as to which wires from the car need to be connected to the harness. I have found the 12v constant (Red/White), the ground (Black), and all the speaker inputs. I have found two other wires (Brown/White and Yellow) that only have power when the key is in. I am assuming one is the 12v switch but I don't know what the other one is for.

This is what the label on top reads:

***********
***HUB 1***
***********
1-Battery
2-Front Left +
3-Front Right +
4-Mic In +
5-Mic In -
6-Antenna Power
7-PWM +
8-Ground
9-Front Left -
10-Front Right -
11-N/C
12-Steering Wheel Ground
13-GM LAN1
14-GM LAN2
***********
***HUB 2***
***********
1-PWM-
2-N/C
3-N/C
4-N/C
5-Rear Left +
6-Rear Right+
7-Mono Mix In+
8-N/C
9-N/C
10-N/C
11-N/C
12-Steering Wheel SW Input
13-Rear Left -
14-Rear Right -
15-Mono Mix In -
16- 16-Acc

Any help is appreciated,

its printed on a sticker on the factory radio.

I know, that is where I got the pinout I posted. The issue I am having is that half of the wires are cut and taped up and the original factory harness is all messed up. I'm trying to find the wire colors to speed up the process.

ah misunderstood, i have an 04 aveo harness diagram, not 09.

I currently can get the head unit to turn on partially. The head unit glows but is not functional. In order to get it to fully work, I have to hit the CD eject button. This is what I have found as far as the wire colors go.

The 12v constant is Red/White.
The PWM + (the 12v switch) is yellow.
The PWM - is green.
Both the GM LAN1 and GM LAN2 are green.
The Antenna is Brown/White.

When I tested both green GM LAN wires, the light on the voltmeter was very dim and flickered very quickly.
The green PWM - also seems to be tied to the dimmer.

If anyone has any advice on how to get the head unit fully functional it would be much appreciated,
Nich

It's cool, I just posted what I have found myself.

just get an aftermarket headunit and go about your day... the oem headunit blows

[petrified.rabbit]

thats how i read it the first time too, but his issue is he doesnt have a way to hook it up as the factory wires arent labelled. and there is no plug.

Haven't been able to really get on the internet as of late so I haven't been able to check this thread. I still only have the head unit semi-functional. The head unit has the power from the 12v constant going, however it still wont turn on until I hit the eject CD button. The other oddity is that the head unit will fully turn on when I have the car only using the battery but as soon as I turn the car on, the head unit goes back to only having the 12v constant for power.

If anyone has any idea how to fix this, it would be appreciated.
