E825 Heater Switch Wiring

Hello All - I’ve replaced my Heater Switch which would no longer remain in the up/down position with a new switch. That’s all good, however the switch does not light up as it should. Wondering if anyone could provide the wiring diagram for the switch connections, so I can make sure all is connected properly (one prong has nothing connected - not sure if that is correct either).
Thanks!

Did you replace the switch with the same factory switch?

Or what did you put in there?

Anyone have a diagram or pic of the wire connections on back of this switch - just to confirm? Not sure if someone had this off before and missed something and just want to confirm its wired correctly.
