I'm off next week so if I remember I'll see if I can lift the fuse box off and take some photos.
Cheers Simon, that will help a lot. Meanwhile i'll source a relay and wiring (what capacity?). Is that all i need? Are there no wiring runs to the ignition switch at all, sounds like its all at the fusebox end? And ... if you forget, i'll remind you
Apoligies Jim, not really relevant to your blog.
I'm sure Jim won't mind his thread being derailed for the umpteenth time, last time I derailed it we were talking about central heating boilers so this is at least about Citroen's, and one of his favourite models.
I checked through my photos and found that I had already taken before and after photos when I did the job which I never posted to the forum. They don't show precise wiring (use the pin numbers on the relay sockets and Jim's wiring diagram for that) but it does at least show some physical context. So here they are. First a view of my fuse box to confirm whether its the same as yours:
On mine the brown relay second from the left is the starter inhibit relay (1005 on Jim's diagram) and I have no spare relay sockets as I too have headlight washers. To confirm its the right relay unplug it and it should disable the starter - you won't even get a click in the start position if you've pulled the right relay.
Wiring under the relays:
Yes all the wires to the brown relay are green

so go by the pin numbers on the socket and if necessary use a multimeter to confirm the voltages do what is expected.
Here is the after view with the new relay/fuse fitted:
The two small wires going to the same terminal on the brown relay is ground for coil negative, in the after shot you can see that it also goes to the new relay coil negative. The large green wire going between the old and new relay is the wire that comes from the ignition switch which has been cut, the ignition switch end goes to coil + on the new relay, the end going to the original relay goes to the non fused relay contact on the new relay. You can see the green fuse plugged into the relay itself on the left hand side, I think I used 30 amp, although I believe the starter solenoid only draws just under 10 amps so 20 amps is probably fine.
You can see a red wire from the new relay sneaking off towards the right, that's the new 12v feed, and goes to the fused relay contact. We'll come to that in a moment...
Here is another view where I've taped the relay and socket up together to make sure the fuse stays in its socket and the relay also stays in its socket (although both are very tight anyway) and is about to be stuffed down inside the box:
As you can see, plenty of room for it. I could have wrapped it in a bit of foam but I was too lazy.

Again the red wire is seen to snake off to the right. So where did I get the new 12v feed from without running a new wire from the battery ?
From here:

This white plug plugs up into the underneath of the right hand section where the small fuses are, towards the front of the car. Here is another view:
On my car this wire seems to feed a fuse slot that doesn't have a fuse and isn't actually used, and goes back directly to the battery. Be careful removing this white plug, it has a clip that holds it in that is not obvious and is quite fiddly to release - I broke the clip on mine before I even realised there was a clip.
Even though it doesn't seem to be used, what I did was to cut the wire an inch down from the plug, and use 3 spade terminals with sheaths, one "piggy back" connector and two spades to go on it to make a 3 way junction, then in addition to the sheath on each spade I wrapped the whole 3 way junction with a few layers of electrical tape to make extra sure it couldn't short to anything then pushed the plug back into its socket on the under side of the fuse tray, with the new red wire running across to the new relay.
Releasing and tipping the fuse tray over enough to get underneath is fiddly and there isn't much spare wire length to work with either, so this is the hardest part of the job, by comparison actually fitting the new relay is a dawdle.
Here's the relay with built in fuse I used:

And I used this flying socket:

As well as that I used standard spade/blade terminals, insulating sheaths, and wire also from the same supplier. You want 2mm^2 (squared) wire gauge, and terminals that will take 1.5 - 2.5mm^2 wire:

Of course you need a crimping tool too. A cheap one is fine:

Hopefully that gives a better idea of what needs to be done.
