I've searched the forum and not come up with the answer, so apologies if I'm recapping...

 

The attached pic seems to be the currently recognised wiring diagram for the inner brake light conversion.

 

 

My question is: to illuminate the converted fog lamp, where have people taken the "Side lights 12volt supply" from?

 

The options as I see them are:

 

1) for each brake light, take the 12V feed from the adjacent side (tail) light, but can the stop-and-tail-lamp-sensor (which is up-stream) handle the extra current drawn?

 

2) tap into the side-light 12V before the sensor

 

3) run a seperate 12V from the side-light fuse (pain in the :x: !)

 

:confused:

No-one got any suggestions?! :tongue:

 

Guess I'll just by a bag of fuses and a fire extinguisher! :rofl:

you should find a pick up point if you take off the right hand cluster on the dash, i converted one of my reverse light into a fog as i wanted to keep the full brake light look, just used a suare of colored plastic and slipped it inside the light throught where the bulb goes took 2 mines to push the film in

Yeah my car's got the same conversion done at the mo, but for aesthetic reasons I want to do the brake light conversion and I'm a little unsure if there's enough balls in the side-light circuit to illuminate a pair of brake lights...?

I used a switchable relay. So under normal conditions the rear lights and brakes work as they should. But when I flick the 'fog light' switch the inner rear lights stay on bright as if the brakes are on and the outers work as normal with the brakes. £8 relay from maplins did the trick.

Yep- use a relay on the brake lights, that's what I'm going to do, but where did you tap in to the side-light 12V feed?

 

Did you just tap in at the lamp assembly? Or did you run a seperate line from somewhere else?

Question by Mark W

can the stop-and-tail-lamp-sensor (which is up-stream) handle the extra current drawn?

 

No it can not, the unit will fail and the right hand rear side light circuit will fail along with it, better to take the power before the preferably from the switch end.

Sorry to bring this up again. I am going to be giving this a shot in a couple of weeks. How can I tell which lines these are from inside the car. ie red for 12v right?

 

Also from looking at the picture, does the 12v supplies for the bake supply and side light supply connect together at the 12v relay.

 

Sorry to be a pain, Im always worried I do something terminal on the car when working with electrics.

On mine I have taken the 12V feed from the actual front fog switch, ( spliced into the wire on the plug that goes into the r/h cluster ).

 

So when you turn the front fogs on this supplies the feed for the rear, and when the sidelights are turned on it also supplies a feed to the rear, its on the same circuit.

 

So that I can turn off the rear fogs and just have the front ones on for the "chav, driving around with your front fogs on in perfect weather" look, I have fitted a simple on/off switch to the rear fogs to turn off the supply to the rear when I don't want it.

 

Its simple to do, just run the correct cable from the front fog switch to the inner rear tail lamp and put an on/off switch in a convenient place for you.

 

Mine works fine and i've had it done for ages with no problems, as long as you use the correct cable then you are fine.

 

that is of course the simple way to do it, if you want to have both brake lights working and the fog lights wired up too then i'm not sure what to do.

 

I have fitted a simple rocker switch in my boot so switch between 4 brake lights and no fogs & 2 brake lights and 2 fogs, I NEVER take my car out in bad weather so the switch is set in the 4 brake light position, for the MOT of if I get caught out in bad weather then I can switch it over to 2 brake lights and 2 fogs, thats just convenient and simple to do for me.

Sounds simple, ill have a look next weekend. Cheers
