Your 2 switches will have 3 terminals each. One will be copper colored and two black. You will require a 12-3 WG wire between the switches. The Travelers: The black terminals will be connected together one from switch a to switch b and the other from switch a to switch b, it does not matter which black terms you choose to go from switch a to b The brass terminals one will go to the light switch a and the other to a power source switch b.

Normally the fog lamp switch (illuminated) has 3 leads: power, accessory, and ground. [b]Power[/b] is connected to existing power when ignition is "on" or "accessory" [b]Accessory[/b] goes to the relay (86) [b]Ground[/b]... goes to a ground. A non-illuminated switch won't have a ground. The relay consists of: (86) - switch (85) - ground to chassis (30) - main power to battery (15 or 20 amp fused) (87) (one or 2) - power to lamps Hope that helps.
Turn switch A on and then wait for a couple minutes. Turn switch A off and switch B on. Go to the attic, one light bulb should be on, that's switch B. Now feel the light bulbs, one should still be warm from having been turned on and then off, that's switch A. The one that's off and cool is switch C.
The inverse of an ordered pair (a,b) is the pair (b,a). So you simply switch the order.
a triangle has 3 sides. the longest side is always C. the other 2 are A and B (which one is which doesn't matter). u can find side C using A squared plus B squared equals C squared. It's basically AxA + BxB =CxC. to find side A, use C squared minus B squared. CxC - BxB = AxA . To find B, use the same equation to find A except switch B with A. CxC - AxA = BxB.-Mathnerd157
Oh, well, simply: max = (a + b + c * 2 + abs(a - b) + abs(a + b - c * 2 + abs(a - b))) / 4;
If you have one wire into your switch box for your light. this is called a switch leg, the dimmer should be wired across the black and white wire wires.
i think light two would turn on because it is in the middle of switch a and b
