anyone help please

engine loom looks like it used to have a secs monator on it but i cant quite decide what has been done to the loom

im geussing that a group A coil was fitted so i can just run those back into single wires for the time being.
but what is the orange cable with what looks like a coil plug on it? it is next to the water temp plug.

also any ideas what the long coiled up cable was for? or what i should do with it?

i bloody hate electrics
