Here is a Guide to fitting a Gen Labs auto Dimmer for Drl's but i have used the auto dimmer module for my ST gauge Pod instead of fitting it to some DRL'S and it is a fantastic little piece of kit, i have drawn a diagram in this Guide for fitting the unit to DRL's but i have used it to dim my gauges and it works 100%
if you are fitting some DRL'S or aftermarket gauges this is a must have piece of kit, and ideal for DRL's to ensure they are road legal and not blinding to other drivers at night.
Here is a link to the one i have used in this guide:
they also offer a kit for the drls that dims the drl's when the indicators are active:
The unit is much smaller than I was expecting, as you can see the size in the picture below when positioned next to the ford key Fob, it fits in to practically anywhere, supplied with a double sided sticky pad for easy mounting to prevent it from rattling around.
The unit comes supplied with instructions for fitting to DRL's so here is an image of what you get in the post:
Below this text is the Diagram i have drawn for the unit to be wired to DRL's
Below this text is the Diagram i have drawn for the unit to be wired to Gauges
if like me you want the gauges to illuminate 100% brightness when the ignition is on,
and automatically dim to 50% Brightness when the interior lights are switched on.
then splice the white cable and the orange cable to each other.
the results will be 100% light on with ignition and when you switch on your lights the gauges will dim to 50% brightness thus less glaring at night giving a nice stock apperance and easier on the eyes when driving at night, while also being clearly visible during the day.
but if you would prefer to have control of when the gauges Dim to 50% you can purchase some cable and a rocker switch from here:
2 Metres of Cable:
12v Rocker Switch:
Insulated Crimp Spade Connectors:
and run the two cables both white and orange to the rocker switch via the additional cable, this will mean that the gauges will illuminate 100% all of the time when the ignition is on,
unless you put the switch to on, then the drls will dim to 50% until you put the switch back off again.
I had already installed my gauges before i realised they were too bright for night driving, so i had to re trace the connections and if this unit in to place,
So i removed the stereo surround and the stereo, taking note of the stereo code prior to removal,
and also removed the switch panel for the rear window de-mister,
where i had spliced in to an interior light positive feed,
i removed the original cable leading to the gauge light positive feed and spliced in the grey feed from the cable instead,
to the positive interior light feed.
Then Splice the Yellow feed from the module, to the Positive feed leading to the Gauge lights.
Only 3 cables left to connect
Next Step is to splice the red feed from the module to the Ignition Positive feed in the car,
i have used the Interior heater controls to obtain an Ignition Positive Feed for the gauges Power,
so i spliced the Red feed from the Module to the Positive ignition feed on the heater controls Coloured Black/Orange
. No Image of this one sorry,
Final Step :
Splice in the Negative feeds from the Module in to the large black feed at the rear of the climate control unit,
i had already spliced a feed to the large black cable for the gauges previous wiring arangment so i spliced in to it instead of making two joints in the original loom.
replace all panels and stereo,
im very happy with the end results, my gauges now illuminate when the key is turned in the ignition, and also automatically Dim at night when the lights are switched on.
