I am collecting parts for this while doing restoration
i have mk4 xr3i efi cabriolet i am looking at buying a complete zetec car focus,escort etc
what i want to know is do i remove the 1600 efi ecu and just plug the zetec one in to efi plug then just change a few wires over at the engine bay plug and then plug the zetec engine loom in and connect up is that correct
what wires do i swop over
thanks
