im using my original interior loom but the engine loom is a fiesta si, not sure where the anti-diesel soleniod is

alright, well the original loom should have one or just go through the fuse box and some of the relays will stay live when cranking, coils don't draw much and you would ideally feed off the fuse box to a relay anyhow to run the lot anyways.
so multimeter to the ready or testing light.
