Had a couple of spare hours this afternoon, so I started stripping the spares car.
Pile of removed inlet gubbins..
Engine bay...
And here's that loom! It looks like I can get away without removing the engine and box, but will need the exhausts off and the gearbox lowered. Not TOO bad (I hope).
In not so good news, I noticed while removing that this loom is also very hard and inflexible. I'm going to ring Ford in the morning to see if the engine loom is still available as a part but if not I'll be checking this one VERY carefully for insulation breaks before fitting it.
