Wiring loom on top of battery............
Discussion
I'm trying to understand the multitude of sockets and relays in the bundle of wires on top of the battery. Everything (for a change) is working fine at the moment but it would be useful to know what these fittings are for the future.
Could anyone add names to the following items, numbered from top to bottom.......
1) Blue rectangular socket,
2) White socket
3) Bundle of wires wrapped in yellow tape
4) Yellow socket.
5) Black socket with green top.
6) Black socket.
7) Blue socket + relay.... Fuel pump relay.
8) Black socket + relay.... ECU relay.
9) Yellow socket.
I believe that 4/5/9 are air con. connections (which my car doesn't have).
Also what is this fuse for? It appears to be the same as the 100 amp fuse for the alternator under the starter motor. What does it protect?
Any help would be much appreciated.

I think that number 2, the white one, is used for a fault code reader.
It would tidy things up a lot if the unused sockets could be removed and the cables terminated and/or shortened - would probably mean unwrapping some of the loom and wrapping again afterwards. I'm not sure that I want to be the guinea pig who tries it though

Any pictures of your battery move and did you not reposition your fuse box? they are a swine to get to.Could anyone add names to the following items, numbered from top to bottom.......

3)Three loops of black wires (earths?) One loop cut for two hot start block connections.
5)One socket in block for hot start earth spade connection.
7) Agree
8) Agree.
Hot start relay + pos fuse holder will make it even more of a jumble, jumble!
Shall try restack the jumble alongside the battery since I have a cut off switch mounted with a perspex bracket on the top rail. There is room, just.

The fuse in the engine bay protects the alternator, the fuse in the footwell protects the fusebox. It's the ultimate generation of wiring in the later cars, as the battery / starter / alt / fusebox circuit has had several layouts.
1 is not a socket, its a connector to jumper together a bunch of circuits.

Wasn't me that posted about fusebox/battery move. Would like to move fusebox behind seat as some others have done (one day). I always keep a pair of long nose pliers handy for a fuse change.So,
1)Loom joint
2)Fault code reader
3)Earth connections
4)Air con.
5)Air con.
6)???????
7)Fuel pump relay
8)Ecu relay
9)Air con.
Anyone know what no.6 is? Also why are the bundled earth wires (no.3) connected to each other and not to an earth point?
Main fuse was opened up just for the photo, but thanks for the heads up.

I would say the bundled earth plug could be used for diagnostic purposes pin-outs etc or further equipment ground points i do know the starter trigger wire is in that plug though live+ so not just earths as said already you have a nice unmolested loom there keep it tidy not like some i have witnessed one 94 Chim in particular i saw for some work 1)Loom joint
2)Fault code reader
3)Earth connections
4)Air con.
5)Air con.

OTOMH 6 is another diagnostic socket (there is a connector for fault reader & another for the Rovercomm or whaterer diagnostic machine IIRC).The earths are clamped to the shell on the LR, as part of the migration to TVR you just interconnect them and run a cable to a good ground somewhere.
The loom is basically post 95 LR Discovery BTW ~ don't confuse with the pre95 with flying lead fuses, I don't know where all the Range Rover comments come from they never had looms like the 95 one since they weren't 14CUX ECU'd at that period.
Did some live volt meter readings of 4),6),and 9) today, for what they are worth?
With battery cut off switch OFF. All 4 connections in each socket was dead. Understandable.
I have a blue 1) but no white 2) There is a white socket near the alternator.
With bat cut off ON, and meter pin on +live bat terminal, and engine NOT started.
4) Had 2 live connections in socket.
6) Had 1 live connection. " "
9) Had 1 live connection. " "
With bat cut off ON, and meter pin on -earth bat terminal, and engine STARTED on tick over.
4) Had no live connections in socket
6) Had 1 live connection. " "
9) Had 1 live connection. " "
I did not do any readings with engine STARTED with meter pin on +live bat terminal. My neck, back, but, eyes and tongue etc all b...dy hurt.
Apart from 6) according to Spend, 4) and 9) dont have a purpose in a non aircon Griff. To make room, these yellow air con sockets could be removed and the wires safely taped up. Yes? Will make room for hot start relay kit. Quandary, quandary, quandary.

The large black relay type thing is probably the passenger light delay unit although mine is yellow, standard Ford unit.
As pointed out above, the layout could depend on the age of your car, I have seen diffferent versions and some a complete mess.
