I am looking to disable the DRLs on my truck, its a US truck that was shipped to Canada, I have looked top to bottom for the relay, its not where it should be in the relay box on the drivers side fender and I have looked everywhere for one that may have been added in under the dash. My assumption was that US trucks did not have the DRLs enabled? But they are on. The truck is an 04 FX4, I had a 97 and was able to just unplug the relay that was tucked up in the drivers side wheel well.

Thanks for the help

 

Why would you want to turn them off? Just searched and in 2 minutes found something. Trucks that do not have the relay have a "loop back plug". This was just a quick search and didnt really try to educate myself on it. Google ford daytime running lights or daytime running lights loop back plug see what you can come up with, and maybe educate US along the way

 

In the fuse panel under the hood, pull the DRL enable relay and the DRL relay.

The DRL enable relay routes power from Fuse #40 through the normally open terminals to the normally closed terminals on the DRL relay, then through the DRL resistor and then to the low beam circuits for the L & R low beams.
The DRL relay coil is powered by the high beams, the Fog lamps or the instrument cluster ( any of the 3 can power the DRL relay, and the normally closed terminals open ). The Instrument cluster is in place of the low beams, as with the DRLs on, this could power the DRL relay, opening it, which would turn off the low beams, which would drop the power to the coil, which would ( see where this goes ).

If you pull both the DRL enable relay and the DRL relay, this will have the circuit to the DRL relay dead, and the DRL resistor dead, which should turn off the DRLs.

Do not see a reason to place a jumper in the DRL relay normally closed position, as this would put power back to the DRL resistor...

 

Why would you disconnect them? Are you taking the seatbelts out too?

 

I hate DRL's! You people in Canada are told when to get up and when to go to bed. We don't have a socialist dictatorship here QUITE YET! They're trying to shove us into the "obedience box" that you Canadians have to live in. To many of us still enjoy freedom! California has earned the name "Left Coast", but at least we don't have DRL's shoved down our throat yet. Keep 'em up there!

 

This is just post whoring / thread crapping.

The question was "how do I", not "should I"......

 

At least you got a truck built to better specs! One built for the Great White North. Hope you enjoy your truck that was made for Canada.

 

What specs are those by chance ?

 

they have snowflakes on the tires...duh...

 

you could always remove the bulbs ???/

 

and put em back in for night?

 

Ford uses a resistor in path to the low beam elements to create the lower wattage DRLs, unlike GM ( trucks ) which uses a different lamp housing for DRLs.

 

Scully- I know you have your ducks in a row when you post a response but do Fords use the LOW beam rather than the HIGH beam for DRL's? All of the cars that we have owned and that I have worked on that have DRL's always used the high beam. (Thank God they have the "DRL off" position on the switch, which we use!)

 

Scully- There IS a difference in the trucks built for the "The Great White North" They have a LOT bigger #'s on that window sticker.

 

The 04-08 looks to be low beam, here is the 2006 EVTM cell 97, never hurts to question or check my work, I can screw up just like the next guy.

EVTM 97-2, follow the circuit from the DRL relay through the DRL resistor to splice S278. Splice S278 seems to join the DRL circuit with the standard low beam circuit from EVTM cell 85.





EVTM Cell 85-1 Headlamps, splice S278 is also noted here :


2 reasons for that :
1. Have to pay for that socialist government and all the give away programs.
They make Cook County's taxing rate look down right reasonable.

2. It is that funny money with animals on it.....That is worth a 2% hit right there.
