Q:I got molds done a while back for my finishing wires on my braces. I'm getting them Tuesday, but I'm not really sure what the difference is between finishing wires and the wires I have now. So I'd be delighted if someone could explain:) Also, after you get finishing wires, about how much longer is it until you get your braces off? And, would you recommend the wire retainers, or the clear ones? Why? Thanks in advance!

Finishing wires are for the final stage of braces. They are pretty strong wires that snap tightly into your brackets so the orthodontist can finely control the teeth and line everything up nicely. I can't say how long until you get your braces off...that's kind of a case by case basis. Typically the wire retainers are better than the clear ones from a hygiene perspective. They can also be adjusted unlike the plastic ones.

Q:I bought Nexxtech Evolution series 16 gauge 30' wire to be able to bring my rear speakers farther back in my room. I have an Altec Lansing 5.1 speaker system with remote and all the speakers connect to the back of the sub. (front are red wire, center is blue, and rear is gray) they are all have the black wire and the colored wire. The wire I just bought are brown, and have a stripe of gray on the second wire (polarized wires) but the ones I bought are much thicker wire... will it still work to just strip/twist/tape the wires to extend the rear speakers? or did I buy the wrong wire? and also, how do I know which to twist with which? (the ones I bought aren't really that clear on which is which... which end is positive and which is negative).Answer quickly please!

First of all, wires really don't make a difference at all - not for speakers anyway. Any cheap wire from home depot will work fine. The stuff they use for lamps works very well. Secondly, the colors, stripes, etc. don't make a difference either. Here's the only thing that matters - make sure you connect the (+) or RED wire from your amp to the (+) or RED terminal on your speaker. Likewise with the other wire. That's all you need to keep track of. If you don't do this, then your bass will suck.

Q:My light switch has three sets of three wires (like conduit).. there are three black wires, three white wires, and three bare wires.. and I don't know how to hook up another light switch because it's near impossible to get three wires around a screw terminal. My boyfriend (works in maintenance) hooked a light switch up (one that you put the wires in a hole and then screw) except for the bare wire where two wires are under the screw terminal and the third is wrapped around the other two bare wires. The lights will stay on but when you turn the switch off, it kicks the breaker.. can anyone tell me why it's doing that? Thank you.

Do you mean you have a lamp or chandelier with three sockets? If that's the case, white and black are positive and negative, and the bare wires are grounds.

Q:Are two wires of the same material but different in thickness and length? Are their young's modulus of elasticity the same?

identicalThe young's modulus depends only on the physical properties of the material itself, irrespective of the thickness or length of the material.Young's modulus characterizing the physical resistance of solid materials to deformation, and the physical quantities characterizing the properties of the material. The young's modulus reflects the rigidity of the material, and the greater the young's modulus, the less deformation it is prone to.I hope I can help you.

Q:having a difficult time finding a wire for my remoter starter

The white wire to the coil is the tach wire. If you have the 4.3L,there is a white wire with a black tracer from the ignition control module to the coil. If that doesn't help,on the PCM,in the red connector,terminal 10 is the tach wire from the PCM to the Instrument cluster,this wire is also white.

Q:first wire change

Depends on how many little kinks he's putting in it. Also depends on how fast he works, if your wire needs a lot of work or a little, and if he already has an idea of what he wants to do or if he's just guessing along the way. It shouldn't take longer for him to make the actual kinks than it does the remove and replace the wire. That's a little more labor intensive and can take about 5-10 minutes for each wire. The whole thing, uninterrupted might last 30-45 minutes.

Q:I am wiring a cd player in my truck is it necessary to get a wire harness that is made for the year make and model of my truck or can I just cut the factory terminals off and just connect the like colors?

While a wiring harness isn't strictly necessary, It's highly recommended. The wiring color code on an aftermarket head unit will match up properly with a vehicle-specific wiring harness. The wire colors of your vehicle wiring will NOT be the same as the wire colors on your aftermarket unit. You have to match the wires up according to function, not according to color.

Q:I recently bought a stereo for my truck. What is a good average gage for a ground wire? Speaker wire? Power wire? Last but not least a speaker control (remote) wire? If it helps, I am running a 760 watt pioneer amp on two 12 inch subs. Thanks

It depends on the size of the amplifier. Recommended wire size should be no less than 10 gauge wire for power and ground. 4 or 8 Gauge power wire you need 4 or 8 gauge ground wire . Speaker wire depends on the speaker. Door speakers should use14-16 gauage speaker wire. Subwoofers should use no less than 12 Gauge speaker wire. Remote wire doesn't need to be big at all use can use 16-18 gauge wire for the installation.

Q:So earlier my passenger low beam wouldn't turn on. i went and bought a circuit tester and found out a wire located here _-_ lt;=== (the bottom right plug on the socket) that wire wont light up. i bought a socket at the same time, but i dont know how to replace it. and even if i did.. i don't see how that would fix the wire.It's possible the wire is fine. but i cleaned the socket and all that and still nothing.any advice would be great. i really need to drive at night1994 GMC jimmy

The wire that leads to your socket may be worn or damaged. Find out which wire is not working. Use a meter that has a sharp probe, so you can stab the wire with the probe and see if it is putting out the electricity, up the wire from where you put the socket on. If the wire is not working, but off the part of the wire that is not working and splice in a new piece of wire and attach to the socket. Hopefully this will help you.

Q:is there a way to wire an exit sign to a plug for an outlet receptacle?

Yes just get an electrical cord with a plug at the end and wire it up. White on white and black on black with wire nuts If you have only the wire with no plug you can buy one and put it together, it's easy to do in the plug the same thing one white wire goes on one screw and the other screw you put the black. It makes on differance what wire goes to what screw only the ground if you have one, which is colored green that goes to the ground screw.
