Help with engine wiring loom

I have purchased an unfinished project, I am putting a standard 1.8 engine back into the GTE.

The engine and engine loom I have got is out of a cavalier and it has a relay and a main battery feed on the loom, with a 4 pin plug.

Does the mk1 Astra engine loom have this relay and battery feed on it? Or is it part of the vehicle loom?

I think I have found the plug on the car to fit the engine loom to by the right hand iner wing

Any help is appreciated

On the astra the engine and car loom can be separated, but I can't remember how they are joined, although a 4 pin plug does sound familiar, they join near the ecu which just behind the fuse box.
The relay on the mk1 is in the engine bay near the header tank.

All earth's as far as I'm aware are brown and in the engine bay for the engine loom.
Are they the power feed for the fuel pump?
