It has 5 connectors and a black round plug.
The 5 connectors go on the injectors and the round plug pushes up from a cut out in the head, when you put the new one in, I always just wipe a tiny bit of oil on the O ring just to help it in and prevent the o ring rolling. It just pushes in.
Then plug the loom back in.
The red plug goes to the ECU. Make sure you disconnect the battery. There's 2 Pozzi screws hold the ecu in, undo those and the whole ecu just slides up and out. Then unplug the red plug and give it a clean. (There may. It be any oil in there)
You need to check first.
