I am just installing my aftermarket stereo.I did the wiring,and I use the 70-2003 wire harness.Everithing works,but no sound.The deck works just fine.I tried a speaker to connect to the deck,and it just worked fine.So I have no idea!Please somebody help me!O!On the harness kit there is two wire what I didn't connected.One is the orange for "ILLUMINATION/DASH LIGHT" ,and theanother one is the orange/white for "DIMMER".So do I have to connect those to somewhere?If yes where?

Now I figured it out that the problem is the factory amp,what I have.Did somebody istalled an aftermarket stereo with the Moons&Tunes?If somebody did,do you have picture of the wiring harness?Thanks!

I believe there're a few theads on that somewhere in this forum, give Mike (ragingfish) a few minutes to get to this post, and he'll tell you about his experiences.And shouldn't that be an 80-2003?

MrRich · Post by **MrRich** » Fri Mar 05, 2004 12:10 pm

I think it is the 70-2003.But maybe we need different with the moon&tunes.Will see.Please somebody!!!!!

Sorry I couldn't help you further via IM, I'm going to upload the wire harness diagram I received from Crutchfield here for reference.There should be someone here to help out further.Post any updates when you can. Good Luck.

Hm. I'd say that's the problem. The harness doesn't have an amp turnon wire, which I believe it should..Hopefully Mike will hop on this thread soon, he's been successful with his system, and i'm sure he'd be happy to help out!PS, when i'm at work tomorrow (at Circuit City), i'll try to take a pic of the harnesses we have and double check the wiring.. I'm pretty sure the M&T amp needs a wire that's not on the diagram Nick has..

I replaced my factory head unit (I have Moon and Tunes as well) with a Kenwood and received the harness exactly like what is pictured in my post above. I had no problems with the audio once spliced into the head unit harness. I'm not exactly sure how the amp is turned on, but I do understand what you mean about the turn on. Let us know what you can find out.

ragingfish · Post by **ragingfish** » Fri Mar 05, 2004 2:49 pm

The harnesses that come from Crutchfield and Metra are all poorly designed. They are missing a pinout for the remote turn on signal. Thus, even if your HU is wired up rpoperly, you'll receive no sound, because none of the pins in the harness are sending a remote turn-on signal to the amp.To correct this, look at the factory harness in the car. One pin on that harness has TWO black wires coming out from it. More specifically, pin #B3. Splice into either one of those wires. Connect that to the remote signal wire from the aftermarket head unit. You should be all set!Let me know if you have any problems...

How about the power antenna wire?It send signal too!Ooooh,I don't know!

Ok!I tried the power antenna wire.But same thing happend.I got that strange shishing noise.It's like it need a filter or something.So I don't know.Any idea guys?

This is where my knowledge here lacks.

I can't for the life of me, Nick, understand why you wouldn' tneed to splice in to the wire to power the amp? You do have M&T right? Makes no sense at all, the Crutchfield harnesses aren't providing that pin...

joatmon · Post by **joatmon** » Sat Mar 06, 2004 4:01 am

I'm not sure what could be the problem, what head unit did you put in, and is there a way to post the wiring diagram that came with it?

MrRich · Post by **MrRich** » Sat Mar 06, 2004 5:42 am

I hooked up the speakers with RCA.It worked just fine.But I had the loud popping noise too.So I guess the stereo is going back on Ebay O!Yes!It is a Koss.I know thy aren't top of the line,but I did give it a try.O well,I guess I have to save some money now!Thanks everybody for the help.

I may have to pull out my HU to see the actual connections, but it was the easiest stereo replacement I have done, other than the powered antenna tweak necessary.I'll definitely check out my install to confirm as soon as I can... got me thinking. MrRich, let us know what route you end up towards and the results!

Jahntassa · Post by **Jahntassa** » Sat Mar 06, 2004 10:49 am

If you go to a Circuit City, you can ask for either an 80-2001 or a 80-2003. They're the same connector, with the exception that the 80-2003 has a switched lead that can be run for Chevy vehicles that don't have switched power in the harness.I do have pictures and can provide a pinout of the stock radio if need be.Nick - If you have the M&T, i'm not sure how you could do it with the diagram Crutchfield sent you, unless the ACTUAL harness had a blue or a blue/white wire on it..which would be the amp turnon.. But hey..stranger things have happened..

Ran it by Jahntassa. I'm gonna try tomorrow pulling out my stereo and reversing the polarity on the RCA's so the center is negative, just to see what happens. While it's uncommon for something to be wired center-negative, stranger things have happened.Before you relist that radio on ebay, lemme give this a shot, and I'll let y'all know tomororw!Was gonna pull out the radio anyway to do that little antenna amp trick, figured might as well give this a shot at the same time!

I got sound just fine (actually I got a little too much sound )See here I'm gonna guess that the 70 series (70-2003) for example, is the non-Circuit-City part number. I think the 80-2003 is the "smart harness" that we use, that has a quick connect on the other end. The 70-2003 must be the part (shown in the pic on the thread you posted), that doesn't have that quick connect, and goes to bare wires.However, I will verify that the harness mentioned IS the 80/70-2003, and does have the remote turn-on wire...As for the popping..gotta leave it with Mike, as I don't have a M&T to experiment with

ragingfish · Post by **ragingfish** » Sat Mar 06, 2004 3:11 pm

The 80-2003 has a blue/white pin on it???

Jahntassa · Post by **Jahntassa** » Sat Mar 06, 2004 3:32 pm

Okay, as I seem to have created confusion, here we go.There are two harnesses available at Circuit City. I'm sure they can be gotten elsewhere, but this is what I've personally physically seen.These two harnesses will work: 80-2002, 80-2003 The difference: The 80-2003 has an extra switched-power wire coming off the one in the harness as some Chevy trucks don't have switched-power in the radio harness.These two following images clearly show the pinouts for the 80-2002/2003 harnesses for the Vibe. Use it as reference to figure out what wires do what on the stock harness. Here you can see which side is "up", as the side without the numbers is the side that the little retaining clip is on.Mike is being kind enough to send me the harness pinout from his service manual, so hopefully that'll shed some light on some of the stranger things that GM decided to do..

Jahntassa · Post by **Jahntassa** » Sat Mar 06, 2004 9:43 pm

Hm...there's one minor difference between the M&T harness and the others... on pin B6, which is a black/white wire on the stock harness..there's a "Sensitivity Control".. I wonder if that's somehow the key to the "popping" the M&Ters keep having..

ragingfish · Post by **ragingfish** » Sun Mar 07, 2004 12:40 am

Good find Joatmon.I sent him the pinout for the harness. So that, combined with aforementioned wiring diagram, should help us decode the mystery that is M&T!

ragingfish · Post by **ragingfish** » Sun Mar 07, 2004 3:49 am

SUCCESS!By simply reversing the RCA polarity - center negative, NOT center positive - popping sound is ELIMINATED!WOOHOO!!!

ragingfish · Post by **ragingfish** » Sun Mar 07, 2004 4:44 am

Alright. Cancel that cheer of joy. It's doing it again. For some reason, when I initially hooked it up, it wasn't doing it. I dunno why. But now it is again. DAMN YOU GM!!!!!
