dfi is coil pack. im used to 4 cylinder with camira coil, so not used to that plug but I reckon you can pick what it plugs too. Yes wideband will need you to add or move a pin at the ecu end. You should be able to re-use the A/C select wire. There is a tutorial for getting the pins out and moving them. Its a pain - you think you have no chance and its just not happening, then it works.

Right.
When I picked up the engine it had a manual trans attached to the back of it, so must have been a conversion.
I'm running a C4 auto, so none pf the ecu components that deal with the factory auto will be needed.

Good excuse for a good pull down rip out all the auto wiring AC add in a wide band connector you won't regret that. It can be a pain getting them into the vehicle at times.

Yea it seems there is a lot that is in the loom but not required.
As long as I get power to the ECU, have all the sensors on the engine and injectors connected, it should be sweet right?
Do the injectors have their own relay?
I have seen one on the diagram but doesn't seem to be one on the loom.

Fed from the body loom. It all makes since once it's opened up.

Ok,
I'll start to open it all up now and see how we go.

Also, the ignition module.
I don't seem to have one?

What does that long black plug - second connector after the firewall bung and near the map sensor connect to on your engine? Its probably on the engine at the moment, and that'll be it.

No there is nothing like that attached to the engine, nor in the collection of components I pulled off the engine before I rebuilt it.
Guessing I'm going to need one of those?

Don't have a module or no wiring on the loom for it?
