i don't have the diagrams you need, there was a CG13 engine loom diagram on here somewhere but i don't know if it will match what you have in your car.
but the way i deal with looms (and so far it has worked every time, from cars to mopeds) take off ALL the black tape and horrible sticky plastic stuff etc so you can see all the wires, use loose cable ties just to keep the wires together, then trace each wire one by one. it takes time but you will fully understand the loom, and there will be no errors, the problems come when the wiring diagrams don't match what you have, which has happened to me pretty much every single time i have tried to use a wiring diagram.
