I tried following a mod on my 01 Z28 for disabling the automatic headlights and it worked except my turn signals wouldn't flash. I tried searching the forums here and came up empty. Anyone fixed this situation before?

Which way did you do it? The easiest way to do it is to pull up the dash and take the sensor out and put a resistor of some sort in there ( used a paper clip) takes not more than 3 minutes and have done it to 10+ LS1's never had a problem with any of them.

Do all four not flash, or just one side?

3 minutes :eek2: beat you buy one :jest: it should be simple, just jump the conector.

I went the soldering route. Piece of cake. No issues what-so-ever afterwards.

I've never pulled the dash before or have I seen the resistor. Any site that has pics?

I did it the hard way lol.... In my old camaro
I made a fuse w/ wires gong to my asr button which doesnt work since I dont have asr... i just flip the button...

That way its still automatic all other times...

Just take out the t-top, remove the 2 phillips screws from the A-pillar next to the locating hole for the t-top, remove the plastic pillar cover or whatever it's called. Then the dash has clips and you just pry it up with your fingers enough to get to the sensor. Cut the wires and splice them together. It'll complete the circuit and you will now be able to have manual control. Once you see under the dash it's a no brainer. I did this on my old car and my buddies camaro, works perfect. My new car wasn't like that, something about whether or not a car was meant to be sold in Canada or not. US cars don't have auto headlights, Canadian ones do. I read it in the owners manual.

That's just the TA, I think all the Camaros use the auto headlights. The TA's have the wires looped together, but no sensor added. If you have no intention of ever using them, then pull the sensor out of the dash and short the wires together. Or, you could fish some wires down from that location and attach a toggle switch to short the wires together.

On my TA, I added a sensor from the junkyard to make my TA have auto lights. It was cool for about one day then got annoying. Luckily I added a toggle switch to control it as well as the DRL. SO 2 toggle switches for me. Everything worked fine.

Did it kill your brake light on the dash? It did mine, but I don't care much.

You'll have to go into more detail because I have no idea what you mean.

You know, the idiot light on the dash board that says "brake". It comes on if you have a brake system failure or if you pull up on the E brake handle. When i removed the DRL, auto headlights box, it also disabled this light on my car.

I've never had a brake system failure, but I do use the parking brake everytime I park (6 speed), so I know what light you mean. It shouldn't have anything to do with the DRL/autoheadlights mod.

BTW, what do you mean you removed the auto headlights box?
Did you remove this module?

Your not supposed to, you can just add a toggle switch and wire it into this box to control the DRL's. If you removed it completely, that may have effected your dash light.

Or else the dash LED just burned out.

Yes, I removed the box completely. He gives a warning on that site that it may take out your dash brake light, and it did. He also said for some people it made their hatch button stop working, but it did not affect mine.

Here's a few pics of the sensor. This is my 98 Z28. I DID NOT have to pull off the drivers side a-pillar cover to get to it, only removee the passenger side and popped up the dash panel from that side, you'll be able to get your hand under there very easily to turn it 1/4 turn and pull it out. As you can see in the second pic, plenty of slack! This doesn't affect the headlight usage via the headlight switch in any way! Basically, the auto headlights are now disabled because the pcm will now think that it's bright outside and never turns them on. I don't know exactly what mod you did, but this is the easiest way to disable the auto headlights as was mentioned above. If your blinkers don't flash, odds are the bulbs are burnt. Remember, if the DRL bulbs are out, the blinkers still won't blink. Blinkers and DRLs are not the same. Hopefully this helps...

On my TA I added that light sensor (the dash has a hole for it) then wired a toggle to short the wires out on either side of the switch. That way you can turn it on or off easily. That is very cool to do. I can now wink my DRL lights during the day when another F-body or vette goes by in the other direction. I'm sure they are thinking, "What the Fu??". :)

While I had the dash pad up I replaced the red LED with a blue one. Looks pretty cool.

You could leave the sensor in place and add a wire tap to short the wires together. Like this style:http://www.darvex.com/miva/graphics/00000001/SQIS8.jpg Then you wouldn't lose the sensor and it is reversable.

Whoops, forgot to mention that in my post. All I did was snip the wires (leave about 2" on each wire from the sensor in case you want to go back to stock). I basically removed the sensor from the circuit and just hardwired the wires together with a butt connector!

connecting these 2 wires together on a camaro, will it disable the headlights from comming on automatically and still have the amber front bumper bulbs lit. or will turn those lights off also.

DRL (amber lights) will still remain lit! That's the beauty of it, disables the headlights and enables the DRLs FULLTIME!

JasonWW

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.

He also said for some people it made their hatch button stop working, but it did not affect mine. The wiring diagrams (2000 F-Platform) show that when you have a manual transmission, ground for the rear compartment lid release relay comes from the parking brake switch. This ground circuit traverses the DRL module on connector C2. So if you have a manual and disconnect C2 it should be impossible to engage the hatch solenoid. And it looks like disconnecting C1 will disable the front turn signal lights (oops!)

Thanks for the info. :hail: It really helped. Now all I need is time off work so I can do this.

JasonWW
03-13-2005, 11:46 AM
Time off? Took me like 30 mins to pull the DRL module out, solder some wires to it, stick it back in and then add the toggle.

To add a jumper to the light sensor is even quicker.

Just busting your chops. :)

Haha, yeah! Bring a butt connector and crimpers to work, and do it on your break. Seriously, you can take a 15 minute break, do this, and still have about 10-12 minutes left (depending how handy you are with the crimpers!)...

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.

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. :thumb:

Much easier to short the wires on the light sensor. No side effects either. That's what the factory recommends. That's how it's done on all the US spec TA's.

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..

in your instructions, you say to soder a wire between A and B, what kind of wire did you use, could i just cut a paper clip really small and use that?

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.

i just dont like how i lost control over my headlights, they gave me a switch want to use it
