Q:I need the wiring diagram for the factory radio of a 2008 ford explorer. i need to know which wires are for the back speakers so i can connect my Hi-Lo converter to it!? thanks

I'm sorry to tell you this but I have searched on several occasions for automobile wiring diagrams and have yet to find one. I don't think they post them on the web. IMO your best bet is a Chilton or Haynes manual for your vehicle. If someone does give you a good site I would be very appreciative if you would forward it to my profile.

Q:ok so i wired the subs to the amp now, the positive (Red) goes to the battery, the ground (Black) is currently grounded to the metal under my drivers seat. My question is does it matter the color wire is that goes to the stereo? Can i use a red or black? Does it really matter? If not, where exactly would i hook it up behind my aftermarket sony headunit?

I was once considering of tapping into the 12v constant on the HU like I do in 95% of the installs i've ever achieved. Are you talking about the far flung wire connection? If so, you commonly mean the accessory wire, now not the steady wire; and to be able to be a hindrance within the Trailblazer in view that there is no accent energy wire in the radio harness. I might recommend using a line output converter that has a developed-in trigger circuit, so it will flip the amp on when it detects an audio signal coming from the head unit. There's no excellent position to connect a faraway wire in a Trailblazer with a manufacturing facility head unit. You could hook up with the accessory vigour output on the key change harness (a thick brown wire) however then the amplifier will flip off with the important thing, alternatively of staying on unless the door is opened like the radio does. The Motorola box is for the Onstar procedure, and there isn't a motive to do something with it at all. Sixteen feet of vigor wire maybe sufficient or would now not; depends upon where you position the amp. The battery and firewall access is on the motive force's part, so in case you maintain the amp on the driver's aspect of the vehicle, you'll in most cases have ample wire.

Q:Trying to wire up a toogle swithch for boat light. Have a positive and negiative wire coming from the battery. I have 2 wires coming out of the toggle switch and two wires coming from the light. What goes where? Thanks

Q:Why are some wires (especially thin ones, like ones connecting a battery pack in a toy) made up of many wires instead of just being one solid piece of metal?

Easier to bend the wire without breaking.

Q:I understand that in a plug you have the earth wire, live wire and neutral wire. But what is the individual job of these wires?? I know how to wire a plug, i just want to know the individual job of each wire. This is not homework, this is something iam teaching myself.Thanks.

The typical U.S. power distribution system has two hot wires coming into your electric panel, plus a neutral wire. The neutral wire is grounded to earth ground, as is the protective green earth wire. An outlet, carrying 110 volts from one of the hot wires (black), supplies current for the load and it flows back to the transformer on the pole normally via the neutral (white) wire to the center transformer (grounded) tap. The green protective wire does nothing in normal operation. However, should the appliance have a metal outer skin, and the machine develops a short, energizing the outer skin, it will flow through the green ground wire back to the transformer rather than through you and back to the transformer.

Q:when we connect the amp wire to the car battery we first remove the negative side then connect the amp wire to the negative side and reconnect the negative battery wire thing. is this correct?

Q:im gettin a amp and sub for my car and was wondering how would i make a wiring kit for it ... i have basic knolage of wires but thats about it thanks in advance

the wiring kit is usually: - low gauge cable of certain length (x2) - rca cable of a certain length (x1) - small power connect cable (x1) seeing as these things are already pretty much in their simplest form, I don't see the practicality of making your own wiring kit. just buy one.

Q:I have a 98 oldsmobile intrigue. Stock radio was taken out a while ago so all there is are wire hanging out. I don't know what I need, a wire connector or wire harness. Honestly don't know what's what. Also need to know how to use the wire connector/harness.and what goes to what

First off, if there are bare wires, meaning they are all loose and you see copper then you are in for a rough time. If they are still wired into the stock harness and connectors it will be much easier. If you have a stock harness and connectors, you should buy a vehicle harness adaptor that is correct for your car. Just about any stereo shop should be able to get them. This will plug into your stock harness and give you labeled wires to connect to the harness you get with the new head unit. Just splice them together and you should be good. Very straight forward. Just follow the instructions. If you have bare wire then you will need to get a chilton's or haynes manual for your car. There should be a wiring diagram that lists the color codes for the what wire is what. Use that to splice into the deck harness. This is the harder route because you don't have a lot of slack on the stock wires and its a headache to keep it all strait in your mind.

Q:How much wire is required?

Length of wire is L = R*A/p SI units must be used, so convert radius to meters: r = 0.0254 / 64 m using 25.4mm = 1 inch r = 3.969*10^-4 m (0.3969mm) So cross-sectional area is A = pi*(3.969*10^-4)^2 m^2 A = 4.95*10^-7 m^2 The average resistivity of nichrome is p = 1.1*10^-6 ohm-meter So the required length of wire is L = 2.2 ohm * 4.95*10^-7 m^2 / 1.1*10^-6 ohm-meter L = 0.990 m

Q:If not, then, in experiments, why must a wire always be straight?

no, not really, perhaps a fraction of a percent if the cross-section narrows down at the bend. And wires can be any shape in an experiment. Who told you they had to be straight? I once told kids in a lab that you used the striped wires for AC and the solid colored ones for DC. A few believed me.
