Q:Im replacing the factory rear speakers in my car but cant figure on which wires are positive and which are negative. I went on a site for impalas but the color wires they have listed are not the same color wires in my car your help will be appreciated.

Left Rear Speaker Positive Wire (+): Brown Left Rear Speaker Negative Wire (-): Yellow Right Rear Speaker Positive Wire (+): Dark Blue Right Rear Speaker Negative Wire (-): Light Blue

Q:Theres a Green Illumination wire from the factory setup, where do I connect that wire too on my aftermarket deck? Also theres a White/Blue wire that I dont know where it connects either?

Metra Wire Harness part number 70-1002 is the wiring harness for your truck.

Q:Hi, I'm extending my pc 5.1 sound system stereo cables. I have a M/F extension wire which I will cut to solder a seamless wire to the system. Problem is that in the system cable I have a white, green(or red) and bare wire. and ont he extension I have a black red and white. Which wire do I connect to which?thanks

It doesn't matter as long as you keep it strait, when ever possable connect a white wire to white wire, red wire to red wire etc...if you have like a green wire original but no green extension wire then I would use green electrical tape to color code the extension wire to the same color as the original, you can buy electrical tape in almost any color and wrap it around the wire and connector ends for color coding...

Q:What are the advantages / disadvantages of different types of wire (ethernet, coax,twisted pair) over the different types of wireless( WI- Fi, bluetooth)

wireless is slower than 10/100 according to readings on p c wireless is mainly for convenence

Q:Hello,I'm trying to replace my old ceiling fan with a new one but i can't seem to figure out the wiring.I have three wires coming out of the ceiling: 1) Two white ones that were connected together when the old ceiling fan was installed2) A grey wireI have four wires in the new fan:1) Black2) Black and White (would connect with the black based on the instructions)3) Green Grounding4) WhiteCan you help me figure out the connections. Thanks!

I wish contractors followed the wiring / building codes. The white wires are neutral wires that return the circuit back to the panel. Grey? where in the world did that come from BUT I have to assume that it's the hot wire from the panel. Black black with the white tracer to your grey wire. White to the white if at all possiable put a screw in the box with the green wire or at least wrap it around the screw from the horseshoe that you are putting in the box. Be sure that the switch is off. If it's wired properly there will be no hot wire in the ceiling box. The hot is open at the switch. That's why the light doesn't turn on. Follow me?

Q:I have two low voltage wires that run from one side of a building to another. The insulation on both wires is the same color. I eventually just walked an additional wire around the building and checked continuity. Is there an easier way to differentiate between the two wires?

Assuming that the two wires are unconnected at both ends. If it was a long way to walk, I'd probably just have connected one wire to earth (or an earth bonded item like a radiator) at the far end and checked for continuity to earth at the local end. A slightly more esoteric way would be to connect a diode between the wires at the remote end. A d.c. continuity check between the two wires at the local end would allow you to deduce which wire was connected to the anode and which to the cathode. A battery between the wires at the far end and a d.c. voltmeter at the local end would do much the same job in that it would tell you which wire was connected to positive! .

Q:I am building an ice chest boombox and want to wire a toggle (on/off) switch to turn the amp on and off....the amp is wired directly to the battery....my question is that I am using 6 gauge wire....but can't find any female spade connectors that are 6 or even 4 gauge to hook to the terminals on the switch.....what is a simple way to do this....am I going to have to solder the wire straight to the terminals?

Why not wire the toggle switch into the remote + wire? The one that turns the amp on and off with the head unit. 7/5/2013**** Leave the power supply wire alone. The thick 4 gauge wire that runs from the battery directly to the amp, leave it alone, don't put a toggle switch inline on that wire. Instead there's a wire from your head unit (or ignition) that runs to your amp, it turns on the amp when the head unit turns on or your ignition key is in the on position. It's usually 16 or 14 gauge. That's the wire where the toggle switch belongs. Look at your amp, this wire I am speaking of is probably labeled remote+ or ign or something like that and it's usually located next to your power and ground connections on the amp.

Q:OK - I removed my old light switch and can see that there are only 2 wires coming out of the wall to be found - 1 white and 1 black. There are absolutely no other wires that I can see back there. The dimmer switch has 2 black wires and 1 green. I'm really not sure what to do. I tried to connect the 2 black ones to the black one and the green wire to the white wire. I admit this wasn't the smartest thing, but thought I'd try. Got nothing. Any help is super appreciated.

Attach black to black and if it doesn't work just switch the two from the switch. The green is the ground wire. Attach it to a screw inside the junction box.

Q:Hi,I'm trying to connect a Panasonic CQ RDP200-LEN car radio. Normally,there is red and yellow wire for ignition and constant,and a black wire for ground. However,this unit has 2 yellow wires,2 black wires and a red. Where do these wires go? thanks

Honest answer is to take it to a audio specialist. finding and wiring a stereo from scratch (termed hardwiring) is a hard job even for the most advanced audio specialist. This is speaking from experience. Most wires are not colour coded and you will need a amp meter to measure the current, voltage, continuity and resistance in order to find out what wire does what. One wrong wire could mean new speakers or in the worst case set fire to your car. I've have done hardwires for over 5 years, and I've seen some real mess, which quite possibly could have been avoided for a few quid but impatience and inexperience has lead to new cables, trim and other pieces which were damaged due to bad installations. Please be careful!! added 9/11/06: (Note To other answeres) Don't use Choc connections or block connectors for wiring stereos as these are open connections with exposed areas of metal if they came into contact with earthed chassis they can cause a short try using bullet style or butt connectors they are more secure and sheilded!

Q:I am installing a Pioneer head unit in a 1997 Nissan Pathfinder. All the wires from the harness to the deck are connected according to color. I was able to connect all of the wires except for the stock orange/black wire coming out of Nissan's harness. I am assuming this wire has something to do with the illumination. The pioneer does not have an orange/black wire to connect it to. The deck will not turn on at all if the orange/black wire is:- not connected to anything- connected to the red power wire- connected to the yellow power wireThe deck will turn on if the orange/black wire is:- connected to the black ground wire- connected to the remote wireHowever when the headlights are turned on the head unit cuts off and will not turn back on until the headlights are shut off again. In other words, the deck will work fine until the headlight switch is turned to the on position. Does anyone know a solution to this problem?Thanks, Dan

This link may not be accurate... The only wire I see in the first link which is close in color is the black/yellow wire for the left rear speaker ground....no black/orange combo shown. Factory ground wire should be grey...test with a test light to confirm Constant power is pink....test also Switched power is blue...test also Once you confirm which wires are power and ground, hook those up to the deck wiring and then run the speaker wires to the proper ones on the factory harness. You can't always connect the same color wires from an add-on deck unit to factory wiring....wiring colors will differ. Consult the installation instructions or call the deck manufacturer tech assistance hotline. Make sure you have the correct wires from the deck hooked up to those factory wires....I'm thinking you have the wrong wire hooked up to the rear speaker ground or deck ground and the unit will only ground when that wire is activated somehow when the light switch is on.... /blue? is the factory illumination wire according to the first link. Have you got that hooked up wrong with the deck ground or speaker?
