the nova loom is now earthed to the body,
the gearbox is earthed to the body
all the 3 earths are on the inlet manifold.

only thing that im a bit confused with is the black multi plug on the xe engine loom. it has various cables in it. including a thick black/red cable for the startor motor, a black switched live for the ecu, the reverse switch, and most of the oil pressure wires and things. it also has a thick brown cable. i thought this was ment to be connected to the thick brown cable on the nova loom. i forgot that that was an earth that was ment to go on the body as the car has been in bits for so long.

what should i connect that thick brown cable from the xe engine loom to?
