Just two questions. I've been translating my wiring diagram for a 2TGEU and can anyone tell me what the Vf pin goes to. On the diagram it joins up with a power and earth wire in something (relay, computer, switch etc). On the Diagram all I can make out is EFI (not much help).
The second question is what does the emmision control computer (OT pin) do, or more importantly is it better to include it back into my engine loom?
