I say that JimW has given you the best answer ..... sounds to me that the box that those wires are in is a connector or in-line jumper box ---- where is your multi-meter or 2-wire/glow tester to find whatz hot .... the certified electrician is going to do what JimW says ... further tests will prove it .......

is it safe to use twist on wire connector to connect my new stereo or should i crimp instead?

I would suppose in this case there is a good better best way to do it. IMO I would never do twists on a stereo, at the very least, do butt connectors. Best way would be to solder each wire one by one and seal with heat shrink. That will give you a very clean look and you'll be proud of yourself :)

I wired up my brothers stereo in his 1994 volvo 850. At the time, I knew nothing about wiring harnesses so I did everything one wire at a time. I got it working but the stereo can still run with the car off. If you turn the radio off, a small led stays lit on the front. My brother couldn't get his car to start this morning. Could this little light be drawing enough power to run the battery dead over night? Should he just get a wiring harness and hook wires up like that?

If the stereo runs even with the ignition turned off, then you have wired a continuous power supply to the radio instead of an accessory, and that will drain his battery. I always recommend using a wiring harness when installing an aftermarket stereo, as there is no way you can accidentally wire something wrong.

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!

I'm trying to wire a Sony L410X stereo to my 2002 Chevy Silverado 1500. I don't want to use a wiring harness, so I'm trying to figure out how to splice the wires together. I don't know how to hook the power wires up correctly. Obviously hooking the speakers up will be easy. I've tried looking at the wiring diagram but it seems like on the stereo system diagram it's positive and negative whereas the truck wiring is not identifying the negative wiring, just 12v+ Constant and 12v+ Switching. Any guidance would be greatly appreciated!

a wiring harness at you local wal mart is like 20 bucks and a lot easier and also using one of them will make sure you have everything hooked upped correct also all audio car dealers use them so there is nothing wrong

my husband is running wire to a hot tub, which uses a 220 plug. he is going to hook up a 30 amp breaker. what size wire should be used?

First thing you need to do is call your city's building inspectors and get necessary permits. !!! For your protection. #10 wire for thirty amp breaker. For 220VAC you will need 3 wire (three conductor cables) plus ground wire for a thirty amp breaker. But question is what is the ampacity rating of your hot tub? You need to size your circuit breaker to the ampacity of your hot tub. Breaker is going to have to be a two pole (double pole) breaker GFCI breaker since it is 220 VAC. since it is for a hot tub. You should have a red wire a black wire a white wire and a bare wire in your cable. The black wire and red wire are your hot wires they go to the breaker. The white wire is your neutral (grounded conductor) it goes to the terminal strip where all the other neutral wires are connected in the breaker box. The bare wire is your ground wire! It goes to the ground wire terminal strip in the breaker box. Now that said if you or your husband is not absolutely sure about what you are doing get an electician to do it for. First water and electricity do not mix at all good together. Good way to get fried if tub goes hot on you if hooked up wrong. Good way to burn the house down if hooked up wrong as well. Another thing since it is a hot tub meaning like wet area like bathrooms and out side special considerations are going to have to be taken for safety namely you are going to have to use a GFCI circuit breaker or have a GFCI double pole switch to disconnect the tub incase of a short circuit or excessive current leakage to ground otherwise you end up bolied lobsters. Well done and ready to eat by the time you are found. Not as easy as just hooking up three wires is it. And if you do not know exaclty what you are doing call an electrician.

Hi,I'm trying to install a ceiling light with a 3 wire configuration (white, black, ground) into a wire configuration of 4 wires (white, red, black, ground). This is configured for two on/off switches.So far, I have white to white, black to black, and ground to ground with the red capped off. This works with one switch perfectly, however when I hit the other switch, the circuit breaker blows.Please help, and thank you!

I think according to your description of the wire configuration what you have is a power supply at the switches and 2 lead wires (red and black) coming up to power the light and fan separately. The white wire, or neutral wire is for a return path while the ground wire is a backup in the event the neutral fails.At the switch in the wall, you should note a black wire (power source) coming to the bottom terminal of any switches. From there, you will find another black or red wire going to the light itself. The neutral wires are all connected together and tucked away in the switch box. If the 4 wire configuration is from the fixture itself, then you would have a black wire for power to the light, a red wire for power to the fan unit while the white is a neutral return. If there is only one wall switch, you could in theory, connect the black and red from the fixture to the power supply coming up from the switch and therefore use the pull chains located on the fixture to turn on the light or fan or both. Failing this, it would be best to call a qualified electrician and protect yourself from what could be a nasty fire. Good Luck.

Is it okay to solder wrapping wire to a mother board, I am just asking because the wires are called WRAPPING.

i think its fine
