2018 Yukon headlight build

[Andy Schmidt]

So. I’ve been reading and trying to find info or pictures on Yukon headlight builds. Have morimoto xb headlights now and they suck. Granted, they are from the first batch to be released but still.

I read on here about a Lightwerks adapter bracket and decided to give it a shot. Upper projector is an MLED bi-led and the lower is a MLED HB. Will be painting everything inside gloss black.

The brackets are a DIRECT install. Other than hunting down mounting hardware, they went right in.

The HB took some massaging being it’s a 3.0” projector and guys were telling me it won’t fit. Only required about a silver dollar size notch on the bottom.

Had to order a 9005 splitter to make both high beams work and have yet to paint them.

Looks good so far. I'd love to pop mine open and black out the chrome shroud around the low beams.

Does the adapter for the lower HB ensure that the cutoff is similar to the upper BI-LED?

The HB is a fat diamond pattern and has a threaded shaft that you attach in the old bulb hole. Once I get the projectors mounted and wired, gonna put them on the truck to aim the seal them up

Yes. This is great and thanks for sharing.

The HID and non-HID projectors that GM uses in their OEM headlights on the K2XX platform are terrible. This projector retrofit will address and resolve the true issue of poor headlight lighting output and performance.

Will you be adding any projector shrouds to the bottom MLED HB projector?

 

[Andy Schmidt]

Yes. I ordered some smaller ones. I initially ordered large gatling. Not enough room. My mini gatlings just came in. I am also redoing the turn/drl/running light. I am putting an XKGlow led tube for a sequential turn for the full C.

 

[CMoore711]

It's not as easy as it may look for the placement of that LED tube along the OEM GMC "C" shape. There are some sharp corners there and it can be difficult to have the LED tube or strip lay flat with LEDs facing outward AND follow the "C" shape correctly. Not all LED strips/tubes are flexible enough to follow that "C" shape exactly and still illuminate and function.

 

[Andy Schmidt]

Yes. I ordered a couple different sets to play with. Definitely aware of the challenges ahead. If not, I’ll but the led boards and reflectors back in.

 

[Andy Schmidt]

I’m sorry for the lack of updates. Been very busy. The paint isn’t perfect, but I’m having the lenses tinted.

 

[Andy Schmidt]

And I finally got around to testing them on the truck.

Now I need to figure out the Hyperflash issue. Sent some emails to have the bcm reprogrammed.

 

[RoadTrip]

It’s great that you had a vision and went for it. Thanks for showing us the results.

Who are you contacting about BCM programming? I’ve contacted a couple of companies, including one that states “they always reply”, but haven’t heard back.

So I’ve sent an inquiry to White Automotive as well as BT Diesel. And I recently found Custom Calibration Engineering. We shall see who responded first.

I thought I noticed that in your video. What's odd is when you have the hazard lights on I don't see any hyperflash, it's only when you were using each turn signal individually; 3 normal blinks then hyperflash.

Do you think it's because the LED DRL/signal strip you used is drawing different power than the stock LED DRL/signal?

What would need to be changed to the BCM to solve the hyperflash issue?

So fun fact about that new strip. You have a 12v and ground wire. And the turn and running light wire. Apparently the 12v wire I chose gets power when the headlights are on. And yes. 4 way hazards are just fine. Apparently there is a setting in the bcm everyone keeps referring to as “incomplete chassis” for like rvs and stuff or work trucks.

 

[Andy Schmidt]

Dropped them off to get tinted

Also got the Hyperflash issue fixed. Got my autosync gen2 from BT diesel works and the programming and license from Custom Calibration Engineering. Headlights and blinkers work. Like a dream.

Why did you have to get both the autosync gen2 AND a license from Custom Calibration Engineering?

Also does the autosync gen2 device have to remained plugged into the OBD port at all times? Or do you plug it in make your adjustments and then you can remove the device?

BT dieselworks sells the device and CCE sells the license to actually program the bcm. The device purchase was just that. When you select 2017+ that just includes a security bypass cable. Then with CCE, you have to give your vin number to be able to change bcm settings.

To do certain functions, it does have to stay plugged in. But when you reprogram your bcm, you can take it off and put it away. I was going to keep it plugged in but every start up would have a prompt on the screen which was annoying. Also, we have a rear entertainment thing to allow the front to show movies and the autosync and that module get turned on the same was. Pissed my wife off.
