Question about Panasonic CQ-C3403U CD Player

1 Answer

I am attempting to intergrate my aftermarket stereo with my 2004 buick century (without onstar) and I do not want to spend the money on an adapter. I have the wiring diagram to let me know which wire are which in my car, but I am not sure what each wire is for on the stereo. I am looking for the "Wiring Diagram" (somthing to let you know what each color coded wire is used) on my panasonic cq c3403u aftermarket stereo.

It sounds as if you are trying to hardwire the aftermarket stereo into the factory wiring which is a bad idea if you are going to cut the plug off the factory harness. An aftermarket harness does not cost that much money, especially in comparison to your car. If you insist on damaging the factory wiring, and all but ensuring you'll have to leave that radio in the car when you try to sell it, nobody will stop you. The nearly universal color codes for aftermarket radio wires is as follows. Front left +/- White, White/Black. Front Right +/- Grey, Grey/Black, Rear left +/- Green, Green/Black, Rear Right +/- Purple, Purple/Black. Yellow is your 12 volt constant (battery), Red is ignition, blue is power antenna (if your car has a power antenna), blue with white strip is amp turn on (if you are going to use an external amp). I wouldn't suggest using illumination and dimmer wires (orange/white and orange) because they have been known to cause damage to people's instrument clusters and other interior lighting, but proceed at your own risk there. Again, it would really be better to just spend a few dollars and get an aftermarket harness--this is what they're designed for, so that you don't cut up your cars factory harness (which are very expensive if they ever need to be replaced, and I imagine you'd want to put the factory radio back in once you get rid of the car, because nobody will pay extra for your aftermarket radio, and most people buying a used car want everything factory so it feels like a new car to them, instead of a reminder that someone else had the car before. Just think about it, but aside from that, I hope the information will be useful to you.

There is for sure a hook up problem my friend. There should be a memory wire that always has power to it even when the car or the ignition is off. Then there is a switched type wire that only comes on when the cars ignition is on. Check both of these wires in the car. Check the car wiring diagram to confirm this. To confirm the wiring in this vehicle, I Good Luck with this install. And if all else fails, don't take a chance and blow out the unit, take it to a pro to be installed.

Can fuel sending connection be accessed thru trunk on 1997 buick lesabre custom

On some vehicles the FUEL PUMP can be accessed from under the rear seat without lower the gas tank. It would help to have more information about what your dealing with. I had trouble with my 1999 buick century, it wouldnt start. it ended up being a fuel delivery issue the shop i took the car to said i need a new fuel pump and sending lines, however i couldnt rationalize spending the money they were asking. I ended up fixing the fuel pump myself without spending any money. I got my infiormation from they have an expert help section, i explained my problem and they sent me a detailed tutorial with a video that made fixing my car a breeze.

Can you put a newer radio in a 2001 yukon

Hi, my research indicates you can install a single din aftermarket head unit in the 2001 Yukon.
A couple of good websites to use are crutchfield and modifiedlife.
Crutchfields will identify exactly what adapters are needed, and modified life has the factory wire colors.
You will need an adapter to fill the space between the aftermarket stereo and the hole left by removing the factory head unit.
You will also need an antenna plug adapter.
I recommend you buy the wire harness pigtail to simplify the installation--this may or may not include the antenna plug adapter.
If you have onstar, you will need an additional adapter.
If you have steering wheel controls, you will need another adapter to keep those.
Keep the above things in mind when selecting a new aftermarket stereo, as you will need one that is compatible with steering wheel controls and onstar, if you have either of those and want them to continue to work with the new stereo.
Crutchfield has an link called "outfit my car" that takes you through a "Turbo tax" style questionaire and tells you what will work and what you will need. here is the link:

Assuming you have a base Yukon, here are your factory wire colors from
2001 GMC Yukon Car Radio Wiring Schematic
