VW Electrics front fog lights
Foglamps:
VW may have fitted a loom in part for front fog lamps - Caravelle's might have this but Transporter vans didn't. The wiring can be checked by inspecting the wiring to the rear fog light switch on the dashboard. If the first switch detent has no connection, then it is possible there is no wiring in the loom. The front fog lights on a Caravelle also use a relay in position 7 on the relay board (in the glovebox). If these wires are connected (even with no replay present)this means there is a wiring loom connection. You will need to trace these wires to the front of the vehicle.
The best thing to do to wire fog lamps would be to make your own loom to avoid any potenial wiring problems, which is easily done. It is a legal requirement that an indicator light is shown on the fog light switch so make sure it is wired into the loom.
Ideally you should run a wire to relay pin 30 from the battery, fused as close to the battery as possible. Then, take a positive feed from the sidelights or from the headlamp switch or bulb holders and run this to pin 86 on the relay. You can fuse the wire from the sidelight circuit if you like as a precaution. From there, take a wire feed off of pin 85, run it to a switch, and finally to earth.
Then, run wiring from pin 87 to your foglamps positive, and earth the negative side of the bulb! Sounds a lot but once you get used to it its easy.
