Find Green/Red wire which will be #5 on the plug and cut it.
Doesn't work on a UK market 1994 850SE.
According to the Haynes manual, there is a 'Dim/Dip regulator' on mine that is specifically part of the DRL function. Since it would probably be dissipating power (about 30 watts), it should be fairly chunky, but I cannot find where it is or any reference to it on the Web (the Haynes manual doesn't give a clue). DOES ANYONE KNOW WHERE TO FIND IT?
Since this dimmer is an extra device that bypasses the light switch, you can even pull the plug off the back of the switch and the pesky lights remain on!!!
This system has one saving grace - the headlamps *aren't quite so bright*, and only come on full brightness when the light switch is set to position 2 (Headlamps).
In desparation, I've done a temporary fix. It's a bit brutal, but since I can't take the fusebox apart, it's the only option I've found so far:
<LEGAL BIT> I offer this 'fix' WITHOUT ANY GUARANTEE OF ANY KIND WHATSOEVER and DISCLAIM ANY LIABILITY IF ANYONE USING THIS INFORMATION SUFFERS LOSS OF ANY KIND. </LEGAL BIT>
1) Take off the fusebox cover (4-no. T25 screws). It is located under the bonnet right by the RH side of the windscreen.
2) Pull out the headlamp relay. It's the largest one, coloured green, that fits into a double socket.
3) Prise off the relay cover. This can be awkward since it is a snap-fit with four tongues of plastic that must all be disengaged simultaneously.
4) Find the pin marked '56b'. It's a 1/4" tab, and is connected via two loops of thick wire to other pins marked '56bL' and '56bR'. (These other pins lead to the headlamp dipped filaments, and the loops of wire are part of the 'lamp fail' warning system - don't damage them in what you are about to do.)
5) Carefully lever up the connection to pin 56b and cut it.
6) Push the severed connection back towards the base of the relay and move it to one side so the connection to pin 56b remains broken. It could then be reinstated at a later date if required.
7) Refit the relay cover, plug in the relay (it will only go in one way round), and refit the fusebox cover.
I would MUCH prefer to keep the dimmer, but only have it functional when the light switch is at position 1 (parking lights) AND the ignition is on. That way, the DRL system functions as normal, but under MY control, for use in bad visibility when motorists are obliged to use headlights anyway, but others would have to use *full brightness* lights.
If I can find this dimming device, it would be fairly simple to do this mod properly.
