I have a 1988 Caravelle GL and so far I can trace the wire from the foglight switch 1st position to the fusebox and through fuse 6 - no relay is installed (position 7) and I can't find any wiring after the relay.
I have looked behind the grille but not found any non connected wires yet!
Have you found wires at the front? ... or coming out of the yellow plug at the back of the fusebox? (should be white/yellow as well).
Once we have sorted this I think it would be good to add to the WIKI! What do you think .. can you take some pics as you do it? .. I will too.

I've been looking into front fogs on my van, and I suspect this is how they are usally done, or in some cases not, on blade fused vans...
There are 2 wireing looms used for front fogs, the dash wireing loom and the front wireing loom. To be able to just plug front fogs in without much wireing involved your van must have both looms wired for front fogs. Some might have one loom but not the other, some might have neather and if your lucky, you've got both already fitted! Posh vans like caravelles are probubly more likely to have them, mines a very late pannel van which luckally seems to have alot of wireing for the extras never fitted already in place. If your missing some wires, best just run an extra cable along where it should go.
If your dash loom is wired for front fogs you'll have 3 wires +earth comming out the fog switch, sounds right from what you describe - this is good!
Next up is to sort the power fead to the switch. If my van is anything to go by, British spec vans (with dimdip headlights) and ONLY rear fogs have the fog relay disconected (aswell as the relay not fitted). The fog switch is instead fed off the headlamp circuit, via [a grey/yellow wire to] terminal M1 on the back of the fusebox. IE the wireing to the foglamps goes...Headlamp circuit>switch>fuse>rear fog. For front fogs you want the switch fed from the relay rather than the headlight circuit (remember your going to be putting an extra 110W through the curcuit so this is important!), therefore it goes...fog relay>switch>fuses and lamps. Unplug this wire from M1 and conect it to the wire coming from pin B20 (should be the same colour), this wire should terminate very soon in a yellow blade conector behind the fusebox - the wire from M1 should plug streight in. Fit a standard 4 pin relay in socket 7 your fogs should now work through that, the rear fog will now work with the sidelamps aswell as headlamps, so long as the ignition is on.
This must be how british vans are wired if they were fitted with front fogs. If your van isn't british spec with dimdip headlamps (a british odity that envolves a different headlamp switch and wireing loom), ie its a LHD import, it looks like you might need do no more than fit relay 7 to convert the foglamp fead, the wireing should cope as standard, test to see if the rear fog works with the sidelights.
Check fuse 6 is fitted and works.
Now for the front loom, if its wired for front fogs there should be a white/yellow wire coming from pin C22 into the front loom, if you don't have this wire the loom isn't wired for front fogs and this is where you need to take your feed from, remember this comes from the switch after the fuse, not the relay! Behind the right hand headlamp there should be a 2 pin conector with White/yellow wire and brown earth wire just hanging there fairly blatently, just waiting for the right hand foglamp to be plugged in. There should be a simular conector behind the left hand headlight but I haven't found it on my van yet, probubly a bit more hidden but as the other side is there it must be somewhere. Remember these plugs will have been exposed for as long as the van has been graceing the salty roads so they could be a bit fured up! The earths will go back to the very popular earth point behind the fusebox - make sure they are clean for best performance (affects all front lights and most other dash electrics!).
Thats all I need to do to fit them anyway (just all that?!) Now all I need to do is find a pair of front foglamps! Tipically that nice pair of new Hella lamps I on ebay has been pulled just before it sold for a low price, "listing error" aparently - I bet it was!
