Electric Window Switch & Motor Wiring?

Hey guys, before I ask i'll quickly state that I have a 1.4 MPi Classic (manual windows, locking etc) and I'm wanting to do an electric window conversion, I've recently bought a set of switches and motors for this, but no wires included, excuse my lack of knowledge as I'm new to this whole thing, but would the wiring kit already be in my door and just waiting for something for it to plug into? Or would I have to order some form of wiring kit? If so, could you possibly point me in the right direction as to getting a hold of one?

Apologies in advance if this is a stupid question, as I said, I'm a novice at this.

Thanks.
