Hi Chris, I have owned 8MA 1298 in Australia for nearly 20 years.
It is in very good original condition, is RHD, and un-restored.
It has a Heated rear window with the Orange push button switch between the clock and ignition switch.
The picture below shows the back of the switch with the light blue wire, and I assume it is the positive that goes through the loom to the rear below the fuse box.
Then you can see the light blue wire emerging from the loom, into a connector and emerges as the light blue wire on the left that goes up to the heated rear window.
And the last picture shows the Orange Dash switch, to turn it on.
Hope this helps
Terry
