Re: wiring

I would think that the "b.up" connection would be the backup connection that stays "hot" always. However, I have no idea what "b.reny" would be and I think techman is right about the "acc" connection.

Re: wiring

The B.reny connects up to an ALWAYS on power source in your car, like right to the battery or a terminal in your fuse panel that is always on even if the key is off, and the acc hooks up to a swiched power sourch, like where the original radio was connected, as the acc is called the memory wire. good Luck

I recently purchased a Pioneer DEH-X7500HD car radio and this is my first time doing this type of installation. I'm having some trouble with the wiring, I have excess wires from the wiring adapter.

Depending on your car the looms are different fron standard wiring on all decks.
Basically you have red which you will connect to a power source with the correct fuse inline. This wire can be taken from the ignition source if you want the deck to work only when the key is in the ignition or directly to a the battery (still with an inline fuse) if you want the deck to play even when the keys are removed from the ignition. This is risky as you might forget to switch off the deck and it will drain the cars main battery.
Next you need to connect the yellow wire to an always on power source or directly to the battery, again with an inline fuse. This wire will allow the deck to retain your settings. The black wire must be connected to any metal eathing point that is connected to the cars body so the deck will be connected to the negative power supply. \
That's the electric current connections done.
You should then have 4 pairs of wires for the speakers, usually green, white, purple and grey. They consist of one strand in a single colour(positive) and one strand of the same colour with a black stripe(negative). These are for your speakers-front right, front left, rear right and rear left. Off hand I'm not sure which colour goes where but it should be on a sicker on the deck or in the manual. Alternatively connect them up and figure it out using fader and balance controls on the deck.
The other wires are blue for an electric antenna or as a signal to an amplifier to switch on.
Sometimes you'll get one for a subwoofer this ones colour varies from deck to deck.
Lastly if your deck can play DVDs or video files there might be a pink one. This is supposed to be connected to the handbrake so that you can only watch video when the car is parked and the handbrake is on.
You can bypass this by connecting to any metal earthing point on the car like the black negative wire.
If you have any other wires they maybe for steering controls and those are dependant on the vehicles wiring configuration, but are not necessary for the deck to operate.
One last thing, instead of connecting directly to all the wires I suggest you get a wired plug leads and wire the deck to one end and the other end to the wires in the car. Take note of wiring both ends to the corresponding pins. This will make it easier if you want to take out the deck and put it back in.
Hope this helps

2005 freightliner columbia. replacing factory radio. All wiring is grey :-( Anyone have a diagram showing what pin is what?

Holding the harness and looking at it as it would plug into the back of the stereo you have 8 wires in the top half of the harness and 4 in Tue bottom. Working left to right on the top half first is the rear left speaker, front left speaker, front right speaker and rear right speaker. The positive speaker wires are on top the negatives are on bottom.

For the lower half of the harness you have 1 wire in the top row and 3 in the bottom. The one on top is the switched wire to turn the stereo on and off with the ignition. The bottom row from left to right is ground, and 2 constant power wires for stereo memory you can use left right or both to connect to your stereo's memory lead. I hope this helps I was looking to and had to map the wires using some educated guessing and a multi-meter.

What color wires go where

To find out what your factory wires on your vehicle are, go to then click on the tab, cables and wires, select your vehicle.
What I do is go to walmart, kmart, target or similar, and get the $5 connector.. It wires to cd player and just plugs into the factory plugins.

Cd player wiring-

Yellow - Direct 12 volt power from battery - keeps memory and channel presets
Red - Wire from ignition to turn on
Black - Ground wire - best to attach to unpainted body metal
Orange - Dimmer - Not used
Blue - Not used unless you have power/electric antenna
Blue with white stripe - Not used unless running an amplifier, then it attaches to rem on amp
Gray - Right Front Positive
Gray/Black Right Front Negative
Purple - Right Rear Positive
Purple/Black - Right Rear Negative
White - Left Front Positive
White/Black - Left Front Negative
Green - Left Rear Positive
Green/Black - Left Rear Negative

Lost my audiovox ACD wiring harness. any help?

My guess, is that you have a metal block of stereo with a receptical for a plug that has all the convienient labels, and no plug.

Fortunately, all is not lost, With a little exploration inside the stereo unit, each connector on the back can be identified. As little as two are necessary to make your stereo operate, most likely eight or ten will get your stereo fully functioning.

It's important to write down solutions and processes as you discover them; then later you can refer to them as a guide in the event that you need to retrace your steps as we go along. By freeing our attention from trying to remember everything, we have more energy to discover new things.

In my teenage days, several decades ago, I was handed many car stereos, with no wiring harnesses and I succeeded in wiring them up, 99% of the time; . . Mabe 98%.

The process is fairly basic, If you're willing to use a screw driver on your stereo; I'd be willing to show you what to do.

If you're more the, "buy a new piece to plug into that socket, then I'd reccomend posting a "Wanted . . " item in Craigslist, I always say, "If they made one, they made a hundred of them, so there's bound to be one around someone willing to part with."

I'll send a picture or two to try this system out, I'll use my desk stereo as a model, it's a Sony CDX-S2210, with no connector, I retrived from the recycling bin , On the inside, all brands have to do essencially the same thing (when it comes to the connectors on the back),

If we can share some clear pictures, this will be 100 times simpler.

That's ok.

Not too bad, 150Kb files is the most we can get right now, this will work well.
More to come, I have to sleep.
