In the movies the people never know exactly which color wire of a bomb to cut to disarm it...but they tend to choose the right one. Which color are you actually supposed to cut? Blue or red?

There are hundreds of different wire color combinations.
If the bomb- maker got ahold of some telephone wire, even the writers would be confused.
Even electricians sometimes use black as Hot (the one with Voltage) and some use red as hot, then if you have green that is ground.
Plus it depends on what type of switch it is. If it is a switch that activates when power is shut off to it, then you cut the power wire and boom. If it is one that activates on a timer then you need to cut either the ground or hot.
In these circumstances, a bomb specialist is needed, since he can identify circuits and see which wire to cut.
In the movies, it does not matter either, if they cut the right one, then it is at the very last second, if they cut the wrong one, it is well before the timer runs out, and it speeds up the timer, then they cut the right one, or have enough time to run out of the building. Then it is more about timing than color.

There is no right color to cut. It depends on who made the bomb and what color wire he decided to use.

Depends on the type of bomb, military, homemade. So many choices and some bombs do not use wires and have fuses that will detonate if you try to remove them, the M-904 nose fuse is a perfect example of that.

Its not either of them. Its always the green wire and if there isn't one then the bomb can't be disabled. Let me know the next time how it works out for you.

It depends on how complicated the bomb is and what color wires the bomb-maker decided to use.
If all the bomb maker did was attach the hot and the neutral in a basic series circuit, then you would cut the hot wire(which according to code is either black or red) and that will disable the bomb. You do not cut the neutral because you can cause a dead short which could send voltage to the bomb and set it off.
However, if the bomb is more complicated(or the bomb-maker has switched/used different colors), then more complicated methods have to be used. You could take the scenario I mentioned earlier, and you could possibly set off the bomb by cutting the hot if the bomb-maker has changed the colors or has designed the bomb so that the hot wire goes into a timer first and activates the bomb when the hot wire is cut(no power).
Typically, the bomb squad has other methods than 'cutting the red or the blue' to handle the bomb situation. They might actually try to detonate the bomb(in an open field) or handle it through a bomb robot.
Most movies(obviously) are mostly unrealistic. The bombs 'conveniently' have a red or blue wire to cut and the cutting the right one is good and the wrong one bad; the bombs are never more complicated than that.
Lethal Weapon 3 is a good example of how Hollywood gets it wrong. Given the characters knew they weren't bomb experts, the bomb itself conveniently has a red and blue wire to cut, along with the digital timer. Typically a skilled bomb-maker wouldn't make it that simple. However, the hurt locker is little more reasonable, since the main character carefully inspects and identifies the right circuit/wire to defuse the bomb.

If it actually does this after driving, yet will idle or you've gotten a elementary difficulty. The torque converter has a lockup snatch in it it really is released via a solenoid once you hit your brakes or drop below a particular speed. that is a fantastically elementary area of have that snatch no longer launch by some diverse opportunities. Have a qualified technician diagnose it, yet make element out of the torque converter snatch.

You'd be in real trouble outside Hollywood. Most real-world wiring jobs use whatever color wire is convenient. It doesn't make any difference because electrons are color blind ☺

Don't try to cut the wire, just realize the truth. There is no wire.

since when has there been a wire to cut in real life, it is only in films and normally there is a button or keypad anyway.

OMG, that is the funniest question. You are joking, right?
