Does anyone know what each of them do and if they are colour coded? I think there are about four of them, but sometimes more.

They are nicknamed suzy lines...as in the girls name.They are for the rear lights and side lights,and for the air brakes on the trailer.They are colour coded but i dont know which is which but i do know they cannot be mixed up as they have different fittings on them.

They are used to keep the trailer and the unit together, There are five of them because one wouldn't be stronger enough.
As with earlier answers, they are indeed called Suzie's because Suzy invented them and they still all belong to her,

Electrics for lights and control, air hoses for the air brakes, and other electronics, like brikes and things.
And yes I'm quite sure they're color coded

called suzies.
Red and yellow are air brakes. they carry air to the brakes.
Green and black are electrical, and the other black, but larger end is the abs/ebs system
