Decided to get down and try to find where my water ingress is coming from today with the weather not being bad and all, and found an aerial taped up behind the parcel shelf ...

Now I wouldnt be too bothered but the car is a `91 16V and it has the bee sting aerial on top at the back. Any idea where the lead from that should come through into the car (behind the dash at any particular point?) and why on earth would that be there in the first place?
Found the water ingress too, looks like its getting in around the heater blower
