Quick question..
Bought a light bar for my pre-facelift TD5 today, Don't have any front fog lights on at the moment, but I've noticed that behind the blank switch (where the front fog light switch would be), there is a plug..
Also there are sockets around where the fog lights would be fitted, question is, can I buy a fog light switch (which I understand is momentary action), connect the spots to the plugs under the car and be good to go?
Any help appreciated.. Thanks
Not too difficult to do, but not that straight forward either.
All Discovery II's are fitted with rear fog lights, not all left the factory with front fog lights, but they do usually have the wiring in place for them.
Without front fog lights, the rear fog lamp switch is fitted at the top of the left-hand side of the instrument binnacle.
When front fog lights are fitted, the switch for them is fitted in this top position and the switch for rear fog lights moves down a position.
Because the switch at the top of the row is shaped differently to the other binnacle switches, when you fit a front fog lamp switch, you also have to fit a different shaped rear fog lamp switch in the position below it.
You also need to make sure that the front fog lights relay and fuse are fitted in the engine compartment fuse box, F3 (15A) and R12 in this diagram -
The front fog lights are controlled by the Body Control Unit (BCU) and can be operated ONLY when the starter switch is at position II and the side or
headlights are also switched on. The fog lights extinguish automatically when the side lights or the starter switch is turned off.
The front fog lights must be enabled in the BCU, using a suitable diagnostics tool plugged in to the OBDII Port.
There are three options for front fog lights in the BCU -
None - The vehicle is not fitted with front fog lamps
No Main - The front fog lamps will operate if the headlamps are on main beam
Main - The front fog lamps will not operate if the headlamps are on main beam
The above 'Non-CLASS' settings are from the Technical Manual in RAVE, but the descriptions for 'Main' and 'No Main' seem to be the wrong way round to me
