If its an EFI loom you have two sorts you can use, flappy box or MAFF on earlier engines.
If its a later GEMS or THOR system from a P38 rangerover forget it as these are tied into the cars BECM and security stuff.
Assuming its an earlier one:
You just need to position and see how it falls on the engine, mostly will be self explanatory.
You then get a fat bunch of wires that go through the bulkhead with a big grommet, mid way along this is a plug with around 5 wires within it, the
loom carries on to a few relays and the EFI multipin plug.
All you need to do once plugged up is provide permanent power, switched power and an earth to the middle plug with 5 wires, not all are needed!
The ECU does not have a crank sensor, it just tosses in fuel with RPM, there will be a wire up front that goes towards the coil that picks this up.

This Link shows the diagram for a 3.9 efi 1984 onwards. This was for the flapper
type airflow meter. and this one is for the mass air flow meter.

thanks guy's
its a hot wire type, i believe its from a 3.9 but the bloke who sold it wo me was a WAN*ER
as the engine was meant to be a 3.9 and i have now found out that its a 3.5 so hoping it still fits.
i will take some pics and add them as i am still a tad lost with the wires that enter inside the kit car.

Early discoveries had 3.5 with hotwire, the loom etc is all the same.
Just grab the bit of loom with the big olug on and work towards the engine side, a couple of foot in you will find the small multiplug as I described
above, this and the EFI live within, everything else is engine bay.
