Finally got round to trying to remove it this evening, we labelled everything up and fed the looms from the bonnet through into the car, unclipped all the loom off of the bulkhead and unclipped the fuse box so now ready to feed the loom out through the fuse box hole but the light is going now so it will have to wait until tommorrow.
We have also realised that the car the loom is being removed from has a different style fuse box from the car the loom will be going into, some 3 doors had the box held in with 4spring clips and some were held with 4 nuts and bolts, at a quick glance it also appears that the fuse box holes are different sizes to each other (although havent actually measured them yet.)
Anyone ever encountered this before? Whats the best way to get around it? Will we need to get hold of the other type of fuse box and connect it to our loom? If that is the case then im thinking that it may be easier to just disconnect the loom from the box now rather than messing about feeding it all out just to have to change the box when it is fitted to the other car.
