Fog light - driving light wiring

Fog light - driving light wiring
Hi guys,
Just looking for an easy way to wire up my fog lights so that when I change them to driving lights they will only come on with the main beams.
I want to keep the foglight switch in circuit and use it to turn the auxilliary driving lights off/on if I wish.
Will it be easy enough to get to the wires I need from the fuse/relay box in the engine bay? I was just going to take a 'feed' from the main beam live to power a relay which will make/break the fog light feed.
If that makes sense
Yea I know I could do this behind the lights, but was hoping to just use all the existing wiring, but just add another relay
Thanks

Yes, that would work, site the relay behind one of the headlights, the only problem will be finding the foglight feed. You'd probably have to go under the dash to get to it.
There is another way, I can send you a wiring diagram if you like, by e-mail, it uses TWO relays and only the wiring that is easily accessible.

That could imply that they are driving lights and not foglights and a previous owner has already done the conversion.

Complete noob question. I have a V3 STi and am thinking of fitting spots. I don't have fogs but am told the wiring is all there.
Ignoring spots for now what would I need to do to fit fogs and get them going? Is it just a case of wiring up the lamps at the front, fishing about under the dash for the correct connector and adding a switch, then fitting a relay in the correct spot?

Maybe, more than likely a PITA, plus once you've bought the fogs, you could have had sonme decent lighting for a bit more money.

I'll have to investigate further on what wiring I do or don't have then take it from there.

You might be as well just wiring in the spots and ignore any wiring that might be there.
Live feed from battery-fuse-relay-lamps, relay switched by live feed from supply to main beam.
Probably easier than trying to trace wires and relays etc, then trying to connect it all up.

just done mine . total success . snip 2 wires on switch white/ yellow and then black/green then take feed form black/yellow on switch to relay under glovebox break white / yellow on relay and connect feed from switch black/yellow , hey prestow spots that only come on with main beam you can turn on and off and the light still works on switch as well

Can you clarify;
The switch you mention is the front fog light switch?
The relay is one you fitted?
Your headlights mainbeam and dipped work as normal, but you can also bring on spots by switching the front foglight switch on when the main beams are on?
