Just a quick one, was laying out loom other day ready for cutting out bits that arent needed and looking where to add my new bits in. So couple of questions with pics if you can help before i pull my hair out with wiring diagrams

Firstly, whats this plug for? It was taped to loom unused. I have a feeling its for ECU on an EFi car, if so which colours do what?



Quick picture showing colours of wires going to back of above connector:

Secondly, what are the coloured connectors on door looms for? I think the black connector is for electric mirrors and red is for central locking if i remember rightly. Doesnt have electric windows but i may fit anyway as i've been told its easy enough if it has either electric mirrors or locking.



Theres been an extra spur added in at some point but im struggling to work out what for, i think there was once an alarm installed. Anyone recognise the above right plug?


Lastly, can you tell me what each of these relay holders is related too? Im sure purple/pinkish one is fuel pump. Not sure on others yet though.




Thats it for now, have couple more regarding Emerald ECU wiring and few other bits but will save them and see how we get on with these first.

Thanks in advance for any help!
