So I have 5 wires: are these correct...
1. Blue/Yellow = SIGNAL. (to speedo) (True Road Speed?)
2. Green = LIVE POWER. (from Ignition Live)
3. Black = Negative EARTH.
4. Grey = SENDER – to the speedo sensor
5. Green/Yellow = ECU – direct to ECU Pin No.6 – Is this the pick up for this is PIN 2 in white/clear 8 flat pin plug TVR engine wire harness?

The hotwire diagrams I have show the feed from the speed sensor as being plain yellow. And yellow from the engine loom multiplug to Pin6 on the ECU.
