Did you get it from Maplins, i.e. part numbers on chimaerapages = Door Solenoids Maplin: YD79L or YD78K ?

Assuming you have bought a 5 wire motor the wires are easily worked out, two of them are for the "motor" itself, usually a blue and green, or a blue and red - depending on make.
The other three wires are a glorified changeover switch, one way when open, reversed when closed, I have seen all sorts of colours used for those depending on make.

Even if the old one has failed the changeover part of it usually still works.
Check the way the old one works first, then the new one and work it out by elimination.

the original colours are blue, green with brown stripe,brown with blue stripe, white with brown stripe and black with red stripe. The new one is made by spal and colours are brown, purple ,black, blue and red. Thanks again for your help.

Going by my previous post I would "guess" that the Spal uses blue & red for the motor.
You could make life easier for yourself by looking for clues at the other side where it is still working.

There are loads of different wiring colour combinations for these door motors, you are asking a lot for someone to remember all of them.
