How do you hook up new black white and green wires to 2 old white wires and 2 old black wires?
More information is needed as to what device you are connecting to what power supply. The only two identifiable wires are the white and green. In North America the white colour is used for the circuit's neutral and the green is used for grounding of devices.
How do you attach a 4 wire power cord to electric dryer?

How does a four wire 240V outlet hook up to a four wire dryer cord?
The two "hot wires" connect just as before. Both black wires will connect where the old black wires were. The white wire will go to neutral, just as before. The green, or Ground wire will connect to the frame of the dryer. Try to find a suitable ground point on the dryer to connect the green wire. Often you'll find a green screw that's intended for the green wire. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any workANDalways use an electricians test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Why would an outlet have two black wires two white wires one red wire and a ground?
The normal colors of a residential outlet are black(hot), white(nuetral), and bare/green(ground). It is common to 'feed thru' an outlet, in other words to bring the power in on one trio of wires tied to the outlet and send it out on another trio of wires also tied to the outlet. If however one white wire is not connected the power will not feed thru properly and whatever outlets are downstream will not work. It is possible to burn up whatever equipment is plugged into the downstream outlets, espiecaly if it is electronic ie; omputers, video equipment etc... Hope this helps. Remember turn off power before working all electrical outlets.
How do you wire a 3-way dimmer switch that has two red wires and one black and one green when the box has two red and two black?
you can only have one dimmer, the other switch needs to be not a dimmer. the green wire is ground, it connects to a bare copper wire found in the box, or to the box itself, if the box is metal. the black wire is"common" it either connects to the wire found in the box that has power in it or to the black wire that goes to the light. the 2 red wires are"travelers" they connect to the wires found in the box that go from switch to switch. if you don't know how to check which wire does what( continuity), it is possible to keep changinging the connections until the switch works. you will want to do this with a conventional switch, and install the dimmer afer you identify what wires are travelers and wich are common. you will destroy a dimmer switch by searching for the right connection. once you have identified the common wires, it will be on the black screw of a 3way switch; you can put that wire on the black wire of the dimmer. one red goes on one traveler, the other on another traveler. there might be a white wire in the box, if it is connected to other white wires and not to the switch, leave it alone. if a single white wire is connected to old switch, it may be a traveler.you will connect a red dimmer wire to this. opening the other switch location will show you if the white wire is used as a traveler.the black wire has to be either power coming in, or the wire going to the light. the reds are just connecting the 2 switches.

You want to re-wire a 1950's fridge plug the wires are coloured black red and green what means what and where goes where?
red is live so therefore now equivalent to brown black is neutral so therefore now equivalent to blue green is earth so now equivalent to the striped yellow/green all old appliances can be rewired using these colours, make sure you fuse the live wire though as some old appliances are not internally fused like they are these days.

If the old block heater cord of a 1988 Honda CRX had two wires and the new end has 3 which colored wires connect the new connector to the old one?
Connect to two wires you have to the the spade connectors and forget the ground connector. The spade connector wires should be black and white. Black to gold and white to silver. If the wires coming from the heater happen to be red and white, then red goes to black. You could buy a simple lamp cord which has only tow wires.
