Got a 2014 silverado & am about to install some Rigid SR-Q2 LED's into the fog light assembly, this guide plus a set of fabbed connectors will help a bunch to make the install right, thx Spurshot!

Check the wattage of the lights you plan to install. If they are much higher than the OEM bulb rating, you should consider adding a relay circuit.

This was on the Duramax forum. I believe it is for a GMT 900. But the principles are likely applicable to a K2. Use this information cautiously. ------------------------------------------------------

OK, After struggling thru the schematics and online mods of past models all evening, I figured it out. This is for a Sierra and should be the same for the Silverado. It involves pushing one Diode in

SR-Q2 wide are pretty low, I am not 100% sure what watts the OEM bulb are though... but i thought they were 35w

 

SR-Q2 Specifications:

 

  • Watts: 34.5
  • Amp Draw: 2.50
  • LED's: 6
  • Raw Lumens: 3030
  • Lux @ 10m: 178.2
  • Beam Distance: 267.0 m
  • Peak Beam Intensity: 17,824 cd

** Edit - Finished the install, seems to work great. I still need to do your foglight highbeam mod but wifey thinks i spent enough time in the shop for one day :)

Stock bulb. is 24 watt. You should be ok. I'm running 33w Rigid DOT lights direct without a relay and have run them for extended time without problems.

ok.. I got it working on my 2016 GMC. Just so there is confusion.. everything is the same as the 2014-2-015. Just the one wire is a sold brown now on the 2016 as mentioned above. But the position ( where to insert the diode) is the exact same as seen on page 1 of this thread.

 

Like GMC-AT, I did this mod on my 2016 Sierra Denali. Went with the 10-18 mod at first. Had fogs with high beams just like spurshot noted on Page 1. But, on the 2016 trucks with Intellibeam, when you turn on fogs, it disables the automatic high beam feature. Damn, this is a really nice option. So with 10-18, you have fogs with high beams and not low beams, IF you want to keep the Intellibeam active. If you don't care about auto high beams, just push the fog light button and you have them on low beam, same as normal.

 

After some thought and research, I switched the diode to the 10-22 location in the brown connector. 22 is the Park Lamp Relay control. In this position, you have fogs with park lamps, low beams and high beams and Intellibeam functions normally. The only thing you are giving up now is that you have fogs on with every light position. You cannot have just your parking lights on. I guess this is OK, because I can't remember the last time I used just the parking lights.

 

Thanks to spurshot and GMC-AT for you input. Now the awesome headlights on the 2016 Sierra produce even more light on the road with the addition of the fogs lamps and Intellibeam functions normally. This is a great mod and highly recommended.

Now you need to replace the fog light assemblies with some better lights. I'm not a fan of the LED replacement bulbs I've seen. The ones I've seen change the beam to where it glares above the original cutoff. TRS makes a direct replacement assembly for the Sierra now. I have the Rigid DOT/SAE lights.

Add a switch to the mod and that will allow you to "kill" the mod when needed.

On a 14/15 truck, I would 100% agree. The OE fog lights are a joke. On the 2016 GMC the OE fog lights are LED and seem to be a pretty good light. They project a narrow beam of light with a sharp flat cutoff line. Not saying they can't be improved on, but they are pretty darn good lights.

Good to hear they've moved forward away from those old lights designed almost a decade ago.

 

If you're interested in other options for them, the TRS snap in replacement fogs are rated at 2400 lumens and have a wide beam to cover the ditches.

I was mistaken. The 2016 is a completely different shape.

Nothing about the 2016 LED lights needs to replaced.. headlights and fogs are just plain awesome from the factory.

Got to agree with GMC-AT. I don't foresee any headlight/fog light updates on my truck. Lights are impressive!

I sure wish General Motors had considered this update when they released the 2014 trucks. My 2015 Sierra's lights are crap! And I've had the technical service bulletin and performed. They are certainly better, but much less than satisfactory to me.

 

Any idea if the 2016 lights will fit in the headlight and fog light areas on the 2015's?

      2018 Sierra 1500 Transfer Case Leak

      By Ryanwehr14 · Posted

      Pretty much zero rust on the truck, the frame is super clean. Non-snowy area of California for its whole life. They didn't mention JB weld specifically, just a silicone style seal.

      Needs a manifold gauge hooked up and the pressures read.   If you don't have one, time to take it to a shop and have it diagnosed.

      2018 Sierra 1500 Transfer Case Leak

      By newdude · Posted

      How rusty is the truck?     The transfer cases on these are an aluminum case.  If its anything like the rear diffs on the 2015-2022 Chevy Trax, those will corrode bad to the point it will push fluid through the housing via corrosion porosity or a crack from age/stress.    We have seen folks over tighten the drain and fill plugs on these transfer cases and crack them that way as well.    So I'd say its a 50/50 shot on re-sealing the case.  If all of the surfaces are good and its not badly corroded, they probably can re-seal it.  GM uses RTV to seal the case halves.   If they mention JB Weld, the issue is the case.  Be it a crack or corrosion.  JB Weld "might" hold if they clean EVERYTHING very well and drain the fluid out of the case and clean the crack and then seal it.

      2018 Sierra 1500 Transfer Case Leak

      By Ryanwehr14 · Posted

      A while back, my truck (2018 GMC Sierra 1500 5.3) went in for an o2 sensor and routine service. The tech identified that my rear output seal on my transfer case was leaking, and recommended I have them replace it. At the time I didn't think anything of it, and had them do the repair. Less than a month later, I noticed that the recently repaired seal was leaking again. I called the shop that did the repair and they warrantied the repair and replaced the same seal again. A few months later, I noticed that once again the same seal leak had come back. It wasn't a great time to bring it in and I ended up just living with it for 6 months or so, noticing small (smaller than a baseball) size oil stains below the truck when it would sit for a while, as well as oil spray on the frame (to the point where it actually took the underbody coating off in that one spot). Finally got around to brining it in again, but this time I took it to a dealership service center since I am in a different part of the state for school. They identified the same output seal leaks and recommended they replace them. They also said there was no scoring on the inside of the transfer case, so it didn't need to be replaced. They chalked up the original repair failures to non oem seals and a job that wasn't done correctly. Now they called and said the seals are holding after driving/sitting for a while, but they found a very small leak in the middle, that they recommended they seal with some kind of silicone/jb weld (not sure what they are using). I haven't picked up the truck yet, but I have been reluctant about this whole repair process because I feel like they are just fixing the same thing that keeps coming back, and I am concerned there could be another root cause for the seal failing. Has anybody else experienced anything like this, or have any ideas on other things that could be the root cause?

      2012 Sierra 1500 AC issues

      By Fishbones · Posted

      I just started having AC issues with my 2012 Sierra. The symptom is blowing warm air on all vents.  Here is what I have checked so far. Compressor clutch appears to be engaging and cycling  I checked all fuses and relay, no issues. The only thing I have notices is the short line that comes from the firewall is very cold / frosted. This line is approximately 12 inches long. The coldness stops when it hits the first line connector. As far as AC compressor - At first start the clutch engages, runs continually, Short AC line frosts up. After idling for several minutes the AC line thaws out some but is still cool and the compressor clutch starts cycling on and off every 5 seconds.  Any suggestions on what to look at next would be appreciated.
