I stripped the baleno loom and wired the trolley tug without using a diagram, I only used the diagram for troubleshooting at the end of the process. This isn't meant to sound like a boast at all - I find wiring as much of a pain as anyone and have no special skills at all, it's just that I think using a diagram is fine if the wiring is in the car and you're trying to find out why something doesn't work, but when the whole baleno loom is laid out on the floor of the garage/lounge room/driveway, it's pretty clear what you need and what you don't.
My method if you have the whole car is to take the whole loom out labelling all the connectors/plugs, then strip away what you don't need, like (I assume) power windows, rear demister, lights, A/C, etcetc, until you are left with the engine loom and the power feeds to it. You won't be left with much.
Much of the wiring you can see here is for the two relays required, one is the main power relay that fires up everything, the other is the fuel pump relay. OTher than ign+ve, -ve, VSS and check engine, there's stuff all else.
In this photo, you can see the engine loom hasn't been disturbed at all. I did end up shortening it, but it wasn't required, I just did it to tidy things up.
You may want to keep the wiring for the thermo fan control, even if you just leave it labelled and coiled up. We didn't however.
