Zetec isn't turbo'd as std though and the mgment can't handle boost, so I'd go for aftermarket mgment, or don't fit the turbo and tune it n/a stylee.

But yeah, for N/A you use the full engine loom from zetec donor, as well as some of the car loom, and you re-wire the fuel pump relay and ignition relay to your ign and perm lives, earth, rev counter, temp guage etc. Then you'll need to fit an injection tank and pump, feed that etc... I do sell the looms ready to "plug and play" though if you're worried about your skills/know how with electrics.

Megasquirt for example is what I'm using on my zetec turbo and you can buy the kits for less than 300 quid, fully mappable ign and fuel, add-ons for boost control fan control water inj etc etc... but you'll still need a loom making up (I do those too btw lol).

Drop me a pm or add me on msn if you wana know more, I got mine running on megasquirt, used a zetec donor loom so if thats the route you're planning I could probably help you save a few quid.
