So I replaced the stereo for the stock OEM one. As I put all the electrical connectors back in, one won't quite reach so I didn't bother forcing it. It's the small one with only 1 wire. What's it for? Everything appears to work without it but just wondered what it was for.

Aerial works. Illumination works.

Could be incredibly wrong, but assuming facelift model, the headunit was used in other Toyotas.

Optional extras across other models would have included CD changers, an extremely primitive sat nav, and steering wheel controls.

It's a PFL. But I think that diagram is incorrect, at least for my car. The previous head unit only had CN700 plugged in and everything worked. The other 3 connectors were left unplugged (because there was no where to plug them in).

Is your PFL an import?  The UK ones had a Sony WX-C570R head unit fitted at the port of entry.  When I still had that unit in my car I met one of the Portbury dock team who fitted them with the Thatcham alarms - car was at Haynes breakfast club and a conversation started!

It's not an import. When I bought the car, it had an after market single DIN (with ISO cables), but the original fascia trim from the Sony WX-C570R was there. I now have the Toyota 58806 (the one I believe is referred to as "Fisher Price"), but for a time a unit from a Land Cruiser which only used one connector.

Ah, that makes sense now.  I get why the FL unit is in a PFL!  Not sure if Toyota did any wiring mods for the FL but hopefully others will help.  Perhaps the Portbury crew tucked that 1 wire bit away when fitting the Sony.
