Reversing camera wiring help please! !

[s410man]

Just bought a reversing camera off ebay

No wiring diagram atall with it!!

I've got 5 wires coming out of the monitor and 3 out of the camera

I'm thinking the black and blue wires aren't needed and that the red wite goes to the battery cos it's got a fuse in it ? but apart from that I'm clueless

Cheers
