Toughy, this may help you. It's an image of the Rover SD1 Efi Circuit showing components and cable colours.

Once you have opened the page click on the RED Temporary Link.

Grab it while you can.

Toughy,

I have the manual for the Range Rover, which has two diagrams for the 88/89 and the 90 Lucas hot wire fuel injection system.
Let me know which one it is, and I can scan it for you.
For information, the only white only wiring appears to be on the vehicle wiring loom side of the wiring diagram. This is normaly a white multi plug, located adjacent to the steering column in a Range Rover. The larger white wire, is as you suspected an ignition feed. The second one from reading the diagram, is linked to this (probably in the plug itself) and is connected to the speed transducer, and wired back in to the plug using a yellow cable.

Hope that helps.

i dont know what year my efi kit is all i do know is that its a flapper system, looking at ramons diagram (thanks for that by the way ramon) i think your right about the two white wires being joined together, if you could scan a flapper diagram it would be appreciated thanks

dont join these wires together , they are at the back of the head ?yes
what they are is the connections for the overrun valve .. if you havent got one fitted you don't need the reley near the coil
get rid of it
the relay connector has 4 wires in square , just connect the black/white to the coil negative and insulate the other 2
hope that makes sense
the loose one is now unused
