iLLmaTic3s

Here is the audio wiring diagram for our car

Radio 12v red/white
Radio Ground black/white
Radio Ignition GMLAN Serial Data
Fact. Amp turn on Pink


LF Speaker(+/-) tan/gray
RF Speaker(+/-) lt. green/drk green
RR Speaker(+/-) drk blue/lght blue
LR Speaker(+/-) brown/yellow

Speaker wiring is on harness or amp
The other wiring is on harness

This Helpful?

If you are wondering what wires on an aftermarket plug are the solid blue is remote turn on (for turning on an amp) and blue with white strip is power antennia (cobalts don't have)

iLLmaTic3s

for some reason he did that and it didnt work...i hope the stock wiring diagram might do something for u..if not have fun with it

Woowoo....got her in and she works like a charm, as does everything else on the car...il take pics when i can find my F'in camera, btw...the aftermarket radio doesnt come on until i turn the key to ignition (just before statring it), assumed that was normal, and when i turn the car off it kills the radio....again not big issues, just varying from the stock h/u....but the speakers sound soooo much better

slowbalt

That is normal for most radios. The sotock one had a timer built in that let it run for a set amout of time or until you open your door. You lose that (as you now know) when you put in a new deck. Do you know what the problem ended up being?

NoleafClover

Yeah, i was given the wrong harness which had just so happened to fit the plug and looked somewhat like it would work, since i hadnt wired a cobalt before...either way it was a harness issue and everything works great now....accept when i go to put the new deck in it wont fit flush because the antenna adapter at the back sticks out against the metal plate thats there..ideas?

slamedham

hey man by chance what harness was it that you used?

is it he GM10B... if so i'm gonan be mad becasue i picked up the GM05B last night...

slowbalt

Had the same issure becaue the deck I got left the rca's sticking way out and hit that metal support. I took an air saw and cut the top of that metal thing and then bent it down. Now everything fits great. I highly doubt that the metal thing was all that important because it isn't a very thick metal. I asked the installer at the shop I work at and he told me to do this. He said that he is having to do this more and more to the newer "all cramed together" cars.

No its not normal for most radios, it has nothing to do with the radio. It has to do with the power source obtained to turn the radio on.

NoLeafClover, connect the red wire you have running to the fuse box to the sunroof fuse (whether you have a sunroof or not there will be a sunroof fuse). That will restore original functionality of the RAP (retained accessory power) and the radio will turn on in acc and not turn off until you open a door, just like stock.

there will not always be a sunroof fuse...my car doesnt have one...i think if you dont have pw or pl then you have no sunroof fuse. i have been trying to find that wirein my car since last september. even have a friend that is a GM tech and brought home his tech 2 and said he cant find one either

NoleafClover

is there any other fuse you can use that will be similar to this one?

NoleafClover

I got the metra harness, 70-2301....not sure about GM, but the same harness for the 04 malibu is the one for the cobalt as is the same mounting bracket

iLLmaTic3s

no accesory in your car..thats really impossible. how would any of your electronics turn on and off with the car? a constant 12v and ground, wont do that job...u need a accesory. im sure u can find something in the car that will do the job. i would help u out but i have all that **** in my car..sunroof,etc. goodluck

Bandit2941

I just figured that all of them have a roof fuse here from what I've read here -- my car has a sunroof so obviously it has a fuse for it. I'm pretty sure I read on here people who have a base model with no power windows and have a sunroof fuse.

Not sure what you would tap in to for an accessory lead if you have a base model without a sunroof......

slowbalt

Wipers! Sure you might not have the delay untill the doors open but it will turn off when the car turns off.

NoleafClover

Well, too be honest i havent checked whether or not i have a sunroof fuse, ive been at work at havent had the time today...i will when i get home and if i do than il just wire it there..if not il figure something out....also..im gonna wire in some interior led's, where should i wire em to?

Bandit2941

That's probably what he has it wired to already. If you tap the wiper fuse, the radio will turn on when the ignition is turned to run (not acc) and will turn off as soon as the car goes off.

NoleafClover

Yeah thats what i had assumed...so i will try and find a better fuse option, such as sunroof...

twitch

where can i find a bracket to tap the fuse? ive been to best buy, home depot, lowes, and autozone and none of them have what i need.

EDIT: nvm, i finally found them at radio shack

Xavipheus

This is the fuse I use to power my amp, its goes on and off with the radio, pretty sweet, use it instead of tapping something else.

hardtocope

so does ur base model have a sunroof fuse?
