Disabling Daytime Running Lights (DRL)

mafd2 · August 15, 2016

You're the first girl I have encountered on this forum. Go make someone a sandwich.

Girl? Lol whatever... Don't know where that comes from but anyway; and yes there are some girls on the forum who have knowledge. This forum has great info and very knowledgeable members but with you just joining in August with only 14 posts and being a newbie, we understand bro. Instead of coming on a forum and bashing members and their posts, absorb the great info here, learn and share whatever it is you have about GM trucks because no one here wants to see childish banter and bashing. It is what it is.

the 2016's have a different connector, but still works the same. put a resistor in the 2 slots that are together and your g2g.

These are the plugs that are under the dash , correct ?

Yes - on the BCM

I like the idea of DRL but don't like it using the main headlights.

I found the wiring for a 2014 Silverado here. Pages 42-45

Does anyone know if I can take the DRL pins out of the plugs and use those wires for some add-on LED's? And would the headlights still operate as normal?

If all you guys want to do is disable the DRL from the SLE headlights just get the harness from gen5. I purchased a conversion harness from them when I had a '14 SLE and put SLT headlights on them. They've been having the '14/'15 DRL disable harness for a while. They also have other harnesses for using LED taillights etc. Here's the description for the DRL harness;

This harness will remove DRL function from your headlamp and can either leave it so your Sierra has no DRL's or we can make it so your fog lights become your DRL's. This harness is needed when installing HID or LED headlight bulbs into your GMC Sierra as there is less voltage during DRL mode which can play havoc with the HID and LED bulbs. This harness is intended for all 2014-2015 GMC Sierra's without the SLT package. If you choose to move the DRL function to your fog lights, your foglights will still operate properly at night via the factory switch.. This harness allows for normal headlight function at night except that you will lose the ability to have just your parking lights on. Anytime the parking lights are now on, your headlights will also be on. We also have this harness with the available option of keeping the foglamps on when the highbeams come on...

Hey guys, just joined up after reading this thread. Alot of great info here! I own a Canadian Silverado and did the pin swap mattblackout suggested. Worked great! Now I would like the option to run just ambers any time I want ( day,night,in park) . My question is would the resistor in the sensor accomplish this? If so how can I get the backlighting and dim ability back? ( I don't have fog lights). Also a put a switch in to turn on off some LED "raptor" lights in my grill and clearance lights. Could I just tie my parking lights into this switch some how? Any help would be great. Thanks in advance.

I own a Canadian silverado also and did the pin swap. I added tow mirrors with amber running lights and used the open pin under the steering wheel that's key on. I begged all of my local dealerships and GM directly to remove the flipping DRL since the vehicle is now owned and operated in the U.S but they really don't care. When I pull into my driveway, I'm shinning my headlights at two of my neighbors houses, if I back in, it's closer to five neighbors that I paint their houses with light. I can turn the lights off in park, but in a drivethrough I'd rather be able to turn them off with the switch...

If you have a 2015 sierra the LEDs are the DRLs, not low beams. If you wish to have the ambers on during the day as well simply turn your light knob one click to the right. The low beam will only turn on if you turn the light knob two clicks to the right, or if the dash sensor sences darkness. If you wish to have ambers only during the day and no LEDs just swap the pins in the connector for the ambers and the LEDs. Now the LEDs will only turn on with night lights (or one click right on the light knob) and the ambers will be on all the time without having to turn the light knob. You can also make the LEDs your turn signals by powering them with the turn signal supply instead of the ambers supply (your LED would be a blinker only and no longer a running light).

Interesting. I've never seen those. Seems like you can do the same pin swap mod I've posted for the 2015 silverados. The detailed instructions are somewhere in the last few pages but basically you need to unplug the connector behind your headlight and switch the wires around inside the connector so that the wire powering the ambers will now power the low beam and the wire powering the low beam will now power the ambers. I'm not sure if your truck has the same wire locations as the Silverado. Unplug the driver side connector to put a test light on the pins, look the passenger side headlight to know when just the amber is on and when just the low beam is on, find out which wire does what

ur talking about the pins on number 8 right ?

No. Check out posts on page 6 (Aug 30th 2014 8:19pm) and page 7 (11:13pm) from "flyin99" he posts pics of the main headlight connector with slots A through H and then a list with lables for each slot. But your truck could be different so use a test light to confirm. Then swap the low beam wire and amber wire in the connector.

So all I have to do is in the harness swap pin B and E on the left and B and E for the right?

also below is for 2015 sierra SLE 4wd
