Are you sure ? I haven't got the wiring diagram in front of me at the mo but i'm pretty sure they all go to main earth point and have ring
connector for bolting down.

No, not at all sure as I don't have either the car or the wiring diagram in front of me, but working on the assumption that the white/black wire
you have going to the ECU is connected to the right pin (white black is normally live on Kwak loom), which unless ECU & loom are mismatched or
have been bastardised has to be correct, then unless there is actually a short within the ECU (never, ever heard of such a thing) then when you feed
the ECU with that live, one of the pins that is subsequently coming live at the ECU HAS to be short circuited to earth, only other possibility is that
when ECU goes live it is connecting a pin to earth that you have a positive feed to.
It's possible it's not one of those 3 "earths" that are the problem, but if not there HAS to be another wire/pin which when
the ECU goes live is either becoming live & is connected to earth or is becoming earthed & you have a live feed going to it.
If the examination of the earths doesn't work I would suggest next remove the feed via the 100 ohm resistor that you have on the grey wire &
see what effect that has
Just one further thought, some Kwak looms have a blue wire rather than grey which is the one you need the 100ohm resistor in series with, have you
checked the wiring dig to see where the grey wire you've added the resistor to is normally connected, the dig should show it going to the
ignition switch if you have the right wire

Hmmm, a few thing to try there over the weekend.
Yes, the grey wire goes from ECU to ign switch and one of the relays, I can also try just powering up the ECU via grey. I will also see if I can
eliminate the earth lead that is causing the problem, trouble is most of the earth's are linked together within the loom but I'm sure
there is a way, it can only come from the same ECU plug that has the white/black feed in it.
Really appreciate your help.

Can I assume that you have an early i.e pre 2003 carbed Z1000?
In which case ignore the grey resistor wire for the time being, that is purely an anti theft device and has nothing to do with the ECU running, with
that wire disconnected the engine won't start, everything else will still run.

It's a 2007 B7 engine,
my main concern is to stop the ECU power fuse blowing at the mo, once I've sorted that the rest should be fairly simple.

Are you 100% sure the USA ECU and UK loom are compatible?

Both the loom and the ECU are from USA
There are 3 earths coming from ECU, all of them blow fuse when conected. Sadly no further forward.

Have you stripped off all the outer covering incase the loom is damaged somewhere?

Well, you are further forward, ok, so the 3 earths are definitely meant to be earths (unless all 3 of them are wrong - I take it they are black with
yellow tracer?)
So look at what is happening, when you give the ecu a feed it is obviously putting a feed onto one of the other cables coming from that single plug,
or it is putting a cable to earth that also has a feed on it (less likely, but possible). You need to strip all outer casing off the loom so you can
actually trace wires, as it's only a single plug, that should give you probably 16 or so wires to trace, check that plug against the wiring
diagram, matching the colours up & following wires thro', there either has to be damage within the loom or there's a wire going where
it shouldn't
It sounds like a ball ache, but given the time & grief you've already invested is relatively minor by comparison

I’m sure you have checked this, but, are you using the correct ampage fuse? Sometimes it’s the simplest stuff that’s overlooked?!
