I allready have got the Haynes manual, but its not helping me identify these wires. sure it does have awiring diagram, but umnless you know what your looking for on the diagram then its not to much help. Yes i did buy a full wiring loom  with the engine.

Range Rover Blues:
Oh, cr4p.  The Haynes is where I look when I get asked this sort of thing.

If you have a complete loom for the EFi then all I can say is if it's in that loom, it's for the engine, if it isn't it's not.

Can you be really descriptive or where these wires are, than I can go look at mine (one of which is a 3.9 retro fit too)

BTW, have you started to connect the wires to the main car loom yet, under the clutch pedal?

muddydigger:
OH Cr*p whats i said too. Yes the engine loom is in the car.The two wies i speek of are a white one and a grey one. they are both into the same conection a black one which is very shiny so it was conected to somethng! they come out of the main loom at the same joint as the earthing points to the engine block, passenger side at manifold height. they both have markins along them but at 4am i cant rember what colour they were. the main loom under the pedal is conected however there is blue conection with has about 3 or 4 wires, that goes no where too. The engine was running last night as sweeet as a nut except it had an occational back fire, after reving reasnably hard,it ran for a good fifteen mins then cut out and wont restart. Testing the wires there appears to be no power supply to the realys main and fuel. If the lambarder sensors wires are red then there appeas to be a tune resistor in them.

Range Rover Blues:
The tune select rtesistor tell the ECU what tune the engine has and wether there are lambda sensors or not.  There will also be anotheri nt he loom to tell the ECU it's a manaul box, unless you have an auto in which case it needs connecting to the cutout switch on the selector.

2 wires, passenger side, manifold height, black connector.  Right, I'll have a look.

Range Rover Blues:
Hang on, front LH corner of the engine bay, they might be for the alternator, one is the excitation wire, the other drives the rev counter.
