I bought a capacitor that is almost the same as the old one. it has the same
capacitence 5 microfahrets and 450v, however the color of the 2 wires are not
the same. the old ones are white and red. the new ones are both gray. Is
there a direction to install the capacitor?

If it's for an AC motor start or run capacitor, there is no polarity, which is probably what you have. If it's an electrolytic cap, then those have polarity and are marked.
