Hi I've just bought a 1998 discovery and noticed on the rear window there are four wires just hanging two each side not connected to any terminals I don't know anyone else with a discovery that I can look at to see how they conect to the glass can anyone help ?
Based on a D 1, They are not for the demister as that has a single wire each side do the screen (supply / earth) much like your hight level brake light with a supply earth only.
As u have just bought the vehicle why not ask the seller.
No wires for a high level brake light on a 1998MY disco, it picks up it's power supply from a bonded track on the glass, similar to the screen element.
It does not have a brake light I have noticed this evening that the two side windows in the boot have demisters on them I presume the two wires each side link up the three windows
