Hi Probably a BMooooore question.
Can you set up lights so that when you flash lights the front fogs come on as well and also when you put on main beam?
If so a wee diagram will help or picture.many thanks.

Can be done, but not easily.
Headlamp flasher works by earthing pin 87 of main beam headlamp relay K3, via pin 10 of the column headlamp switch, which is connected by a brown wire to earth.
Only way I can think of doing it, is to insert a resistor into this brown wire which develops slightly more than 0.6V across it when the flash switch is pulled. This voltage would be applied to a simple transistor amplifier controlling a relay which would switch 12V+ to the junction of fuses 29 and 30, the fog light fuses.
There's already a blocking diode in the foglight relay K8 to prevent this voltage backfeeding to the dipped beam headlamps.

I new you would have an answer but it is a bit to complicated for me.I thought it might be something simple like bridging a couple off pins + some solder.Thanks and sorry for waisting your time.
