Hello Ladies and Gents --

Attached is a photograph of the panel light switch in a 1963 Jaguar E-Type. Backside of the toggle switch. I have the wiring diagram, of course, wherein the wires are connected to specific terminal numbers. What I don't know is which of these four terminals [on the actual switch] correspond to which numbers [ on the schematic.] For reference, in my photo, one terminal is currently connected, and the other three terminals are not. Can anyone shed some light? (pun)

Terminal 4 should be power. The black part of the switch should have numbers on it near the terminal.
The rest of the wires can go one any terminal.
You can run a meter though the switch to determine the power terminal if needed.
 
Thank you MK1. Not wanting to unseat the switch from the panel (so as to see the terminal numbers, which I didn't even know were there), I went at the disconnected switch with an ohmmeter. Determined the proper power terminal that way, and also the interconnectivity of the other terminals. Thereby also located the dim-vs-full-bright terminals ... although having switched to LED panel lights, the 'dim' feature no longer works. Of course.

Thank you again for the reply! Cheerio.
