Having checked the S13 fuel pump relay, the black/purple wire is the Power/trigger wire that comes from the ECU. I now have to extend that from the white plug to the boot. I have now wired in several OE connectors to the larger (12v perm and switched wires and made up my three relays. It will simply be a case of plugging in the connectors when the engines in.
I do however have a couple of wires left to do :

1. Is Orange start signal wire from the White plug (by the ecu) that I have to re-route down to the Brown/grey connectors as the start signal on the S12 (8 pin under the AFM Black/yellow wire).
2. The Neutral switch. I know its the Green/Orange wire (brown plug) but I cant find the corresponding wire.
