Turning off automatic headlights

Let me explain a little. The light sensor is what's called a photoresistor. It's like a variable resisitor.
When light is present, resistance is low to nill.
When it DOESN'T see light, the resistance gets higher to the point the headlight circuit is turned on.
By shorting out the 2 wires together, the DRL module thinks it is daytime 24 hours a day. Therefore the headlights will not come on and the DRL's will work just as they always have in the daytime. Make sense?
In order to make the DRL's go off, you have to short 2 circuit board points inside the DRL module. This bypasses the DRL module without any negative side effects. Since the DRL module also controls the autoheadlights circuit, when you deactivate the DRL circuit it also deactivates the autoheadlights. That's why you can't have the autoheadlights working, but DRL's off. You CAN have it the other way around ,though, with DRL's working, but no autoheadlights.
Hope that helps, if not, just PM me.

go to a dealership and ask them, when mine went out, they said there was some kind of switch connected to the E brake, if u notice the lights don't go on until u put the E brake down, and when mine went out the was no problem with any blinkersor anything else.

And it looks like disconnecting C1 will disable the front turn signal lights (oops!)
I disconnected C2, I have no DRLs, no auto headlights, and no e brake dash light. But my trunk release still works.

if you want to turn off your automatic headlights and only have to turn them on by using the light switch, then there is a black box right behind the radio. just pull out the radio and there is a black box with two lines going to it pull out the one to the left i think it is, and if your turn signals dont work just pull the other wire and plug the other one back in. cover it with electrical tape and your good to go. worked for me, since i have halos i had to do it.

After seeing a lot of people driving in rain/fog and near darkness without any lights whatsoever, I'm glad vehicles are equipped with DRL's. Besides, the headlamps only come on when they need to anyway..no big deal..

You could probably tin a small piece of paper clip and use that. Or run wires from there to a toggle switch to have control over it.
