but if you don't have the instructions, as the fog lights on a car bumper you have just bought would not come with instructions.
You will need some crimps (inline or bullet) and also a crimper.
Attach wires to fog's connectors, may require soldering.
Feed the wire neatly around the engine bay through into the car dash, where the switch should be located.
Solder onto switch PIN. The solder another bit of wire to PIN2. Or if you just cut the original wire then carry on with it.
The place an inline fuse by cutting the live wire. crimp the fuse inline with the live, then crimp (rounded) and attach/screw onto battery.
The -ve/black wire can go to an earth point on the car, but i would recommend it goes to the -ve/negitive side of the battery!
Hope this helps.
I will be doing mine soon hopefully.
Also i think i might be coming up by you on the 15th jan or round abouts.
