Thanks for your advice Old Red Celica. It was much more of an issue than I would have thought it would be but at least I have power to that socket now.
Its a little big though and to be honest I preferred the unobtrusive look of my little original lighter. But, when I plug that in - its brand new still, having never been used, When it heats up it doesnt just pop out, it shoots out and bounces around the interior. Also, when I remove the sat nav the whole unit comes with the lead as it will not seat securely AND I had to cut two of the plugs
to make it compatible with my existing wiring set up. so, I think I am going to contact ams on the forum and ask him to supply me a genuine OLD Toyota part.
This is my original part and its obvious its never been used so I am assuming its original...
You were right about the white flash going through the cable to identify it as earth. The same goes for green with a white flash so I am assuming its throughout the whole electrical system - without taking that for granted.
Thank you again friend,
Mark
