I got a new <2004> E350 Extended PSD < Power Stroke Diesel> 6 L turbo, A/C, ABS, 4 Wheel Disk brakes. Anyone know how to disable the DLRs in ACC key postion ? Amps suck enough power from batts as is without headlights on TOO. Was late for work the other day listening to tunes . And not really into letting the whole world know I 'm sitting in truck rockin the parking lot cause headlights are on.

 

one click of the emergency (parking) brake turns them off usually

 

Sorry forgot to mention that li'l detail . Park brake doesn't stop DRLs from comming on

 

then you'll have to unplug the DRL module

 

Ok .... Where is it ??? I can't find a Haynes or Chilton mannual for this truck. I was linked to a site on a different forum that showed the loc for a gasser. No joy on mine .

 

well not positive on yours, but if you follow your headlight wires to a box appx twice the size of a regular relay, that'll be it, shouldn't be much else in the headlight system unless you have auto light sensing headlights.....I'm trying to find an exact location for you and the best method of bypassing....but it might take a bit.

 

K Thanks

 

drl module should be located under the drivers side frame rail close to the bumper your going to need a device called a usa plug, go to your local ford dealer and they will know exactly what your talking about

 

Gota wait till after weekend now. Enjoy Turkey Day all !

 

GOT IT ! Relay is located on the front top rad cradle. I had to remove the plastic shroud and there it was .
