Right It's now becoming clear...
The VDO twin sensor fits here...

and I use the T piece with the White & Blue temp senors in one of these holes in the top of the Oil filter housing - Here;

And I run a wire from the Temp gauge to the Blue topped temp unit and another wire to the 2nd spade on the VDO sensor to the pressure gauge...
Yeah....
Thanks Guys....

Very Helpful...
