I don’t think you will have a connect2 plug. It’s aftermarket. Never one on any of the early cars I looked at. I’m guessing that the phone, mentioned above, was not the LR fitted one. The standard one had an eject box in the centre console and a telephone control module in the boot, with its own loom.

I have still got the original phone in the centre console (not working) of course the service is non-existent now.

All the wiring and the phone module is still there and even the phone hand piece....just there for looks. 😁
