ABS wiring loom/harness is separate to the main loom, theres a plug near the battery tray, fan heater box which is yellow. on this loom you'll find the 2 pressure sensors. The fuse/relay would be in the main fuse box.

I've got my ABS fully removed, But taped up the ABS loom and left it in situ.

Are you wanting to fit this loom, If not you should remove every ABS item, as if anything is left on and the tester see this he should fail the car.

Does the ABS light come off with the handbrake, Also if you remove the ABS bulb the handbrake light will always stay on.
