1974 109 siii ffr ex mod light switch/harness question

[Tasi Autele]

Hello, I am building the siii ffr up and am on the headlight switch. I am going between two wiring diagrams. The original 24v and the 12v. The pic is the harness coming from the rover. Is there anything special I need to know or is it just a standard switch? I have the switch and the harness however I do not have the plug from the back of the switch to this 6 plug. Any suggestions. This also is a pic of the fan switch with 3 settings that looks like the light switch. Also why is it 6 plugs and there is only lo, hi, and off on the switch?

Thanks Tasi
