MCS Ignition and Wiring Loom problem

[Krispi]

I was due to take delivery of my new MCS today when I got a ring from the leasing company (who have arranged the purchase) to say it wouldn't be delivered because they couldn't start it when they went to put it on the transport!

Turns out there is a problem with the Ignition System, and to fix it they are going to have to replace the Wiring Loom. The garage is going to carry out the work when the receive the new part tomorrow, then hopefully deliver the car in the afternoon.

My question is, what should I check when I get this car delivered? Especially now I know the garage has carried out this work, does anyone know what this wiring loom does?

Thanks!
