The motor is earthed by a wire to one of the screws holding the glass. The power lead goes to a plug in a banana socket (unplug when windscreen is folded flat) on the horizontal panel at the top of the bulkhead, and thence to behind the instruments to connect to the dash harness. The dash harness joins it to the fused side of the single fuse in these models, together with the fuel gauge and stop lights. Power for this fuse is from the ignition switch together with the ignition.
Just to confirm - these systems, up to chassis suffix 'C', have only one fuse, and all other circuits except for those mentioned are unfused.
Both the examples I have here have the banana plug/socket missing, and I seem to remember these being troublesome and only available as Rover parts (different size to the ones from your electronics store). Because of the lack of fusing, burnt wiring is commonplace on Series Landrovers up to this date - and later Series 2a are not much better!
