I finished my installation a couple days ago. I had a Morimoto kit in the SLT halogen projector headlights. My limited use of these LED headlights leads me to believe they are not quite the output of the Morimoto kit in the SLT headlights. But they seem adequate. I like the reliability of led.

I just purchased these. I been following along with most of the post. I do want more info about the harness needed to make the DRL shut off when turn signals are active. Do I still need to purchase the Gen5 harness or Is there another harness that I can buy that is plug and play, that will control the DRL w/turn signals?

Since you have an SLE you will need the Gen5 harness.

Thanks zmnypit for the harness. I love the look of these on the 2014's.

Anyone had low beam issues with the light not coming on? Local guy got in touch with me yesterday after buying a 2015 2500 denali that already had the swap done. It looks like a gen5 or plain&simple harness not sure. The drivers side low beam will not power on with that harness or my adapter however the bright light will.  I took the light and ran a jumper to the battery and the low beam will power on like that. Everything but low beam works so I'm scratching my head. Using a test light its getting power all the way to the light so it has to be in the light itself. I ran out of daylight so I didn't get to swap sides to see if I could rule out the light.

Mine works perfectly with your harness

Is there power through his harness to the low side? When you said you jumped power into the low side pin did you use a harness? Or run a wire directly into the low pin?

 

it sounds like a worn pic connection lamp side (if you have power to it) or a broken wire in the main truck harness.

Yep. All the way to the light. I jumped both the light and the existing harness. Main truck harness is getting power at the factory plug as well. Low beams will not power on though even though it gets power. Pass side works fine.

He's supposed to find out where the lights/harness came from then check with whoever. I'm not certain who's it is to be honest.

Are you saying that power is there for the low beam at the OM wires, and if you connect to the headlight only (no other harness) there is still no low beam?

Well I cant connect the headlight with no harness because of the plug differences but yes thats correct. On the OEM fat plug I get power on the low beam, Add either my adapter or his harness and I get power on the low beam on the newstyle plug.

Got it, here is the good and bad of the new LED headlight, Good is there LED for both the Hi and Low beams, the bad is there LED for the Hi and low beams, so we think the computer on the headlight went bad, and lost a circuit in side that controls the low beam, looked it the one we opened here at the shop, it runs all the wires from the LED board to the computer on the side of the headlight.
