I found the easiest way to do it mate was to unwrap every thing and cable tie it back together as you go. It was pretty easy to do in the car.

Then cut the MFI connectors off, and any others you don't need, then pull all the wires through the cable ties and out.

Make a list of what you do and don't need but tbh is fairly obvious when you start cutting lol

I have made a sub loom for efi, so essentially the engine loom is only for lights, oil light, water temp, starter, alternator etc then the sub loom it for all ecu sensors, injectors, fans etc.

Much easier to have two looms IMO

You will be staggered at how much mfi shizzle there is, all my sticky wires filled a bin liner.

Will find some pics
