hi buddy have splice'd efi looms into mk3 before quite easy these a ecu pement live on red and a ignition live black these can be found on the efi engine loom to interior loom connector 8 wire connector on the engine bulkhead there is a green wire for revo will have to doublle check what the other wires are for, why would you want to run a dizzy seems pointless going half the way as the ecu alters the fueling and sparc in sync and would imagine would get confused also for the work thats involved ie changing flywheel for one with cps teeth for crank sensor you might aswell put the coil pack on
