Does anyone know that while using a three pin adaptor with an older version that has a pos. and neg wire any different to the latest adaptor shown with just a Pos clip?

Trying to connect to an old ph1 Spider requiring Three pin.

I have recently crossed into a problem that the red adapter I have does not fit , its too small . I always thought they all fitted the interface.
Perhaps just different to Alfa GT or a bad purchase . Has anyone come across this and can anyone direct me to the correct fitment. KL A2 P3

Maybe I should re-phrase that , I can access my old login details , because my email has changed and therefore cant reset password , can anyone advise please.

I am wanting to access my login details but my email has changed .
What canI do to resolve this please.
