Relay Reconnection
Discussion
Again many thanks for your replies
.
Today took the switch out and found only two wires attached to the switch, a ground and a wire that becomes live when the headlights are switched on, I presume I am missing a feed to the relay.
Question do I really need a relay, would an in line fuse not be sufficient?

In which case there is a very good chance that the side/head switch switches negatives
The relay has been fitted to send a positive down to the rear fog light
In summary........
Relay should have
Terminal 30 - Fused battery supply
Terminal 87 - Cable to rear fog lamp
Terminal 86 - Fused battery supply (Link it with short cable to Relay Terminal 30)
Terminal 85 - Switched negative from fog light switch
Other side of fog light switch should be connected to side/head switch that becomes negative when switching lights on

There could be another option
Listen while you turn the sidelights on/off and you may well hear a tail lights relay clicking behind a kick panel where the fusebox and relays are located, the tail lights relay switches a positive down to the number plate lights and tail lights (first position of side/head switch)
You could pick-up the switched positive from the tail lights relay and wire it to a rear fog lamp switch, now you would be able to switch that positive down to the rear fog light

Thanks for everyones advice.
Fixed it yesterday, started tracing the wire from the fog light to the switch, The switch was disconnected from the fog light, the wire was 2ft to short to reach the light switch!
Looked up its MoT history, it failed its MoT for non operating fog light in 2009, wasn't MoTed 2013, 14 and 16
