I have a 1.8 Zetec focus with a St engine fitted, The engine was running on 1.8 management so i have purchased the St loom and Ecu, Before fitting them i am woundering which part of the loom the VVT plug should be on and if there is another way of wiring the switch up to enable the VVT to work?

Also any help would be appreciated on what i will need to change along with the main harness from the ECU, I have noticed one of the plugs on the St loom which goes to the under bonnet fuse box is different so i will have to change the box, Does anyone know what effect changing the fuse box will have... I.e will i have to change anything else?

Thanks in advance
