I presume the connectors are to separate the vehicle loom from the engine loom, so they can prefit the engine loom before it all goes into the car?? Bit like the big connectors under the bonnet vent on Escos (another totally toss position!! )

I PM'd Stu last night, but don't think he's picked up the message yet -
