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

Where is my ground wire located on my fuel pump on 86 buick century 2.5L got 3 wire the green wire in the middle in the hot wire help pleae

Q:i got this switch with numbers 1 , 2, 3, and 4 on it and 4 wires red, green, and two black. Which wires go to which number?

Well it is defintely a 3 way switch. The fourth (green) wire being the ground. I can't tell you by the numbers, but I can tell you by the screws which wire goes where. If it does not apply to your switch you may need to go get a new one. They are inexpensive. The green, ground wire goes to the screw that is usually attached to the arms ( metal extentions that hold against the sheet rock. Now you need to find the red and black wire that are together. Look inside the box where the wires come in and you should be able to tell if the red and black are in the same sheathing. These are your travelers. The travelers need to go on the two screws that are across from eachother. One goes on the right side and one goes on the left. Does not matter which side. The last black wire, depending on which of the two 3 ways you are at is either your power or your light leg (wire going to your light). This wire goes on the last screw. Hope this was helpful.

Q:How do you properly wrap copper wires? We have been using electrical tape and it's melting the tape. This is in a camper, and it's in the electrical box. We're using this tape because the wires kept touching and arcing off of each other...I'm guessing :/

It is not how you wrap the wires. It is how you connect them. You should use wire nuts or wire crimpers or splice joints. The tape is melting 'cause you are getting a loose connection and causing sparks. Once you get the wires tight you should cover the joints with electrical tape to keep the wires from touching any thing that they should not be touching..

Q:My house is wired for surround sound. The wires coming out of the speakers holes are not labeled as far as i can tell but the wires that are coming out of housing that go into the back of the receiver are labeled 26,27,30,and 31. I cant tell which wires go to which speaker Front Left, Front Right, Rear left or Rear Right. Do these numbers mean anything?

Easy fix: Wire and mount all the speakers, without the grill if possible. The grill will be added later. Get an old 9v battery. Grab the first wire, like 26 for example and strip the wires back about 1/4 inch. and twist each wire. With a helper in the center of the room, tap the wire ends intermittently to the battery. DO NOT KEEP THE BATTERY WIRED TO THE SPEAKER FOR MORE THAN SHORT PERIODS OF TIME. 1-2 SECONDS ONLY. Have the helper tell which speaker is making noise. Have them move to that speaker and take note if the woofer is moving IN or OUT when making sound. If the woofer is moving OUT, take note which wire is touching the POSITIVE post of the battery and wire the speaker to the corresponding output on the receiver. If the woofer is moving IN during sound, switch the wires on the battery and mark the positive. The receiver should remain OFF during setup. Repeat these steps for all the speakers and mark the cables with speaker locations AND positive / negative I.D. with a small piece of tape for future reference. Replace the grills and power up the receiver to set the sound levels. Good luck.

Q:just need a little help to make right.just wiring an outlet from building to breaker box outside.. which way is the right way to wire it to a breaker then the box. Got the right breaker. Thanks

This doesn't sound like an easy answer without seeing it. For instance, how long is the wire run; is it entirely outside (if so, then you'll need either conduit for the full run, or UF-B rated wire buried below the freeze line with conduit where it exits the ground to the Service Panel). Outside receptacles should also be GFCI (Ground Fault Circuit Interrupter) protected. A single pole 20amp breaker should be used for a 12/3 wire. Load wire (black) goes into the screw of the breaker; the neutral (white) wire screws into the neutral bus bar of the service panel (breaker box), and the bare ground wire screws into the ground bus bar. Since these wires are interchangeable, it really doesn't matter which side of the panel you hook the neutral and ground wire to. BE CAREFUL!!!!! The main bus bars can still be hot (charged) even with the power turned off. If you ground yourself and touch the wrong thing, you'll be wondering what went wrong from the great beyond. Get a basic electricity book from Home Depot, or look on youtube. If you're not 100% confident, please leave this to a professional.

Q:i heard there are many diferent copper wire but i only know 2 kinds.1 is for eletric and the other is for crafts.So what else is there?

Copper wire is a metal and is used in electric and electronics compounds. so, that it can flow electricity very easily as it is a good conductor of elctricity, this is a type of a metal in which there are many type of content present in the same and it is cadmium free copper as well as also know with the name Electrolyte Copper which is 100% pure. There are many types of copper wire like:- Plain copper wire Tin-coated copper wire Braided copper wire Tinsel copper wire Bunched copper wire Braided copper wire etc..

Q:I did an engine swap with some friends and everything is in place, from the rebuild 700R4 w/ a shift kit, to the rebuild 350 bored .30 over. But all I have left to do is the wiring, but have no idea how to. So about how much would it cost to have a professional finish the wiring?

The wiring on a basic carburated non emissions engine is pretty basic...it's something you could do by yourself in your garage. Anyone that has any knowledge in wiring and electricity could wire it up. Don't let it scare you! :)

Q:A potential difference of 13 V is found to produce a current of 0.37 A in a 3.1 m length of wire with a uniform radius of 0.42 cm.(a) What is the resistance of the wire? (b) What is the resistivity of the wire? Please show work.

P. D. applied = V = 13 V Current produced = I = 0.37 A (a) Resistance of the wire = R = V / I = 13/0.37 = 35.14 Ohm (b) R = ρL/A = (ρL) / π r?) = ρ = (R A) / L = R (π r?) / L ......... (1) R = Resistance of the wire = 35.14 Ohm , L = length of the wire = 3.1 m A = Area of cross-section of the wire = π r? r = radius of cross-section of the wire = 0.42 cm = 0.0042 m ρ = Resistivity of the wire in Ohm-m Substitute the values in the formula (1) and calculate. Take π = 3.14

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:when u first get braces do they put the bands and the wire or just the bands cuz im getting them monday

You get the brackets with bands and the wire. Rubber bands, though, come later.
