dual brand wiring issues

I am trying to install a Dual brand cd player in my 2000 Chevy Cavalier. I got the wiring harness adapter & everything, but the radio doesn't have anything for the dimmer/illumination wires to connect to. I read in other threads that these wires weren't necessary, but I'm wondering with this radio model if they are - the unit is getting power, it will accept & eject a cd, but I get no display or sound output. All the wires on the harness that come from the radio are connected. I'm left with a blue, BLACK/ white, orange & ORANGE / white wire on the Scosche harness. If I'm mistaken in figuring out the problem, I'm definitely open to suggestions. I had the radio tested where I purchased it and it lit up & had sound on their test set up.

The wires (excluding speaker wires) coming from the radio are:

Blue - Remote turn on
Black - Ground
Red - Accessory
Yellow - Memory

Any kind of help would be greatly appreciated since taking it to a pro is cost prohibitive.

Thanks,
Tiffany

hook the BLACK/ white wire up to the ground, it is the factory amp ground wire. Hook the blue to the blue/white wire, on some it is the factory amp turn on wire. do nothing with the orange & ORANGE / while, exept cap them off.

OR better idea

take a hammer to the dual, then to your hand, as a reminder never to buy one again, & get a quality unit.

they call it dual, cause you gotta install 2 of em before 1 works

afterthought here, but check to see it you have 12V on the acc (red) wire. you may have to tap the fuse box to get it.

I know Dual isn't the greatest brand, but it would sure beat the complete silence I've tolerated the last 2 years since my 1st after market unit was stolen.

Thank you for the helpful advice, though.

One more question regarding the suggested connections. Should I try those connections in place of the black to black etc. that I have now, or am I connecting 3 wires? Thanks again.

Hey geisha..if im not mistaken i think chevy started the rap harness that year on cars...the trucks didnt start till 2003...so i think bass i right...check to see if your red wire is getting power. if you dont have a DMM tie the red and yellow wire together and see if the unit even turns on. if it does then  youll have to get into the fuse box for ignition.

The way it's wired now, it's getting power, there's just no display or sound output. The little red light on the unit itself blinks as it's supposed to when the faceplate isn't in place.

Sounds like a bad head unit to me, then... You've eliminated all of the other options. Short of replacing the unit with another (it'll be easy, now that you have all of the wires an harnesses connected) you could troubleshoot further, forever.

Return the unit to where you bought it, and they should be able to just replace it for you.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

That's just it though, when it didn't light up initially, I took it in & they connected it to their test set up & the display worked & there was sound produced, so they wouldn't allow me to return it - hence the endless troubleshooting.

yeah, sounds like no power on the red wire...just to clarify what jrod said, tie the red & yellow wires coming from the deck together, & hook them to the yellow wire from the car side (no connection to the red wire on the car side). you should then have to push the source button to turn the deck on & off. This will let you know if the red wire has power or not.

Okay, thanks for that tip. I'll try it soon and report back.
