blue/white from ecu(pin28 i think from memory) - pin 85
ignition feed - pin 86
Fused supply straight from battery - pin 30
fuel pump + terminal- pin 87

the old ford black/red will also need to be connected to pin 87 as this also powers the iscv etc. make sure you isolate it boot end to prevent short circuit.

i used a Durite 40/70 amp relay part No. 0-728-70

hope this helps,
