Q:i'm building a race car out of a buick century and the tail lights wires got cut, come to find out the fuel pump ties into the talight wiring harness, i found the wires going to the fuel pump but i'm not sure what is what, there's 4 wires going to it, black, black with a white strip, gray, and pur any ideas what is what please so i can just run a switch to the fuel pump... thanks

Examine the wires at the fuel pump junction on top of the fuel tank. I'd bet one of the wires is the GREY wire. Another way you can determine which is which, get a Digital Volt Meter (DVM) and turn on the lights. Check to see which line has power. That's the line for the tail lights. Then have someone step on the brake pedal. Another wire should go hot (have voltage on the DVM). Slowly you will be able to figure out which wire does what. The left over wires (likely two) are for the fuel pump. Good luck. :)

Q:can aluminum wiring catch on fire

It can be, but you have to be careful when ever you replace an outlet or switch that you get the one that is special for aluminum wiring, other wise it can be a fire hazard. It is no longer allowed by code for new homes, but existing homes are safe as long as you understand the limitations.

Q:instead of using the wire its self could you put a terminal at the end of your audio wire and connect it to the amp, for your car audio. Because I just ordered 1/0 awg wire, but I don't think the wire will fit on the amp, so could I put a Y terminal at the end of my 1/0 gauge wire and connect that to my amp?

you can look on OKorder too.

Q:Any instructions on how to make rings, necklaces, and bracelets out of colored telephone wire.

Q:I have a universal 02 sensor 4 wire (black, black, white and blue) the stock is white black and grey how do I wire it? thanks :)

Keep in mind the sensor has a signal wire, a ground wire and a heater wire (or wires). Good luck!

Q:I'm replacing the ground wire in a chandelier because it has been cut by the previous owner when it was removed from the ceiling. Overall it is pretty simple and I have everything diagramed. When I went to Radio Shack and bought the replacement wire they gave me 18 gauge solid insulated hookup wire. It looks totally different. The ground wire is a braided copper wire (7 strands). Should I go back and take my copper wire with me and get copper or is what I have just as good? An electrician will do the installation of the chandelier into the ceiling.

Radio Shack's hookup wire is copper, but it may be tinned so it has a silver/chrome color instead of a copper color. Tinned wire is more expensive but is also more resistant to corrosion. Braided wire is more flexible than solid wire, but either will do the job. The only real important consideration is the gauge of the wire. You want to make sure your new ground wire is at least as thick as the old one.

Q:I notice my 10/100 Ethernet wire uses 4 wires (2 twisted pairs). I'm curious what each wire is used for. I understand one pair is for Tx (transmit) and the other for Rx (receive) but why does it need 2 wires for each? I assume bits of data cross on one, but what of the other?

This is an ethernet only cable. A full patch lead has 8 cables. Yours is STILL an ethernet cable. The additional blue pair would be telephone and the brown pair was unused, but is commonly used for power over ethernet now. ANY data connection requires 2 cables to balance the signal. In effect one is pushing voltage while the other is pulling and vice versa. One is signal, in effect the other is a ground, bur the idea is that by using twisted pair cables the inductive voltage created in one polarity on one is cancelled by the inductive voltage returning on the other in opposite polarity. The same rule applies to external interference from other equipment as these are also cancelled. If it used one cable and a common ground you can never guarantee this immunity to interference.

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.

Q:I noticed when looking at the wiring sticking out of the end of one of my laptop power cables (the end that enters the battery), that of the green, grey and pink cables there, the green one had snapped. However, my laptop power still works fine, so what does that green wire do exactly?? Is it dangerous to use it even with that wire snapped?

Power requires two wires, but a third wire called a ground wire is sometimes added. Usually the plug that goes into the wall has two or three prongs. If it has two prongs, no ground wire added. If it has three prongs, the ground wire is added. The ground is usually used when metal frames or cases are used. The purpose is to ground or short out the live (hot) wire should it accidentally come into contact with the metal frame, causing the circuit breaker to trip. If the ground wire was not there, it would allow a person to get shocked should they touch the metal frame.

Q:I have a set of two rotating beacon lights on my truck. I would like to wire these directly to the vehicle with an on/off switch. I picked up a two prong toggle switch from autozone, as well as some wire. I'm not sure how I need to do the wiring. I read somewhere about running wire from the fuse box? And how about grounding?

Run a wire from the positive side of the battery to one of the prongs on the switch. Then attach another wire from the other prong going to the light. Take one wire from each light and wire them together. Then take the other 2 wires and wire them together. On those lights positive and negative don't matter. Now take one set of the wires you put together and attach them to the wire from the switch and the other set of wires ground them anywhere on the vehicle.
