Not yet. I haven't had a chance to mess with my truck lately.  I went with a mictuning 32" led from Amazon.  I caught it on sale for $35.  

 

If I think of it, I'm going to try and call Rough Country this week to see about ordering their mounting kit.  That looks to be the best option besides a diy route. 

on your 32" bar what's the depth ??? I had a single bar 31 L X 2 H X 3 D , NO room to mount it .between grill / shutters, maybe your bar is smaller ?

Have you seen the Michael J Fox Edition Sierra/Silverado rolling down the road? Looks like the Toyota from Back to the Future. Anyway there is a really cool headlight switch with the option for Off-Ro

For you guys with 2014/2015 or anyone else that this doesn’t work for (due to BCMs not being programmed to output these triggers), please be patient with us. We have an alternate method that allows

Ok folks, for anyone wanting this headlight switch harness, I have them ready made, and ready to ship.   $35 shipped anywhere in the US.   They are built with the same specs as shown in the vide

I'd have to measure it when I get home. Unless the Amazon link gives the depth.   I don't have shutters, but when doing a dry fit I didn't notice any fitment issues.

My hat is off to Tinkering Fox and Phil Gamboa. The video is fantastic.  I have a 2018 Sierra SLT and ordered the switch and made the harness (sorry Phil).  At first it didn't work, nothing coming out of the X5:5 BCM connector and no indicator light on the instrument panel.  After checking continuity I found that I had to reorient my new X1:12 connector.  I had to turn it 180 degrees in the X1 (white) plug.  Evidently it wasn't making good contact with the BCM pin.  Once I did this, everything works like it should.  If you have issues, check for continuity at each connector.  You can check continuity on the ground (-) signals with you multimeter.  The yellow wire in Tinkering Fox's drawing X5:5 is a +12v signal.  Keep in mind that the BCM triggers (turns on) with a ground, not a positive voltage. I also installed an interposing momentary relay for the high beams to interupt the power to the off road light, so there is no delay in killing my lightbar when meeting oncoming traffic.  I would still like to know how Tinkering Fox knows what functions are in the factory BCM programming and the pin placements.  I can't find any of this information in the Upfitters guides.  Great job guys!

Would the interposing momentary relay work in conjunction with the automatic high beams? I’m interested in being able to have the light bar shut off when the headlights dim and then have to reactivate manually.

That is why I did that.  I used a "Tap a Fuse" to tap into one of the high beam cicuits in the underhand fusebox to power the coil on the momentary relay with the power for the lightbar circuit routed through the contacts and then on to the lightbar.  It is pretty simple.

Wow!  What a huge and informative post!  Very nice!  I'm looking to buy a blue switch, preferably the new 84168423 version - I'm in Canada.  Is there anyone still looking to sell theirs? PM me if you have something.  Thanks again for the great info.

I got my oem orl switch installed. Didn't get the light bar installed because I ordered the wrong one. Just my luck. Anyway, I was messing with the switch to make sure it activated the in-dash indicator light. I noticed the orl wouldn't turn on unless I turned on the fog lights. I was wondering if this is normal? I haven't read anything about that happening in my research. On the plus side I just have to tap the fog light button to turn both lights off instead of holding the orl for 2 seconds. Update: looks like that is when the headlights are off.

Just ordered my OEM switch as I couldn't find one avail online - $170CA !!! A far cry from the $25USD listed at the start of this in 2018!  Looking fwd to the final product though.

The $25 one was from an eBay seller that has a surplus of these. The retail price for the newer version is around $90-$125 USD.

I'm just late to the party!  Oh well, I want to make it look as clean and factory as possible, so I'll wait for my switch to come into the local GM dealership.

I finally did it. Took all day, what a pain to take the front front grille off and modify for the shutters. Pics to follow when it’s light outside.

Photographic evidence for proof. It’s not a UV light but it’ll probably kill some retinas. This is exactly the setup that I wanted, huge thanks to pgamboa, tinkeringfox, and other who did this and figured it out before I took a crack at it. I also got to assess the full extent of the damage from the deer I hit two years ago (two months after I bought the truck). It seems other than a cracked grille I also broke the lower mounting brackets for the grille, looks like I would have to replace the whole radiator support/shroud to fix. Also looks like a big pain in the rear.  Anyone have experience with that? 4F9AE4D6-121C-418A-B4FA-41AB5D744142.jpeg.5c0b56040f3e6e0d809a4a5f05620aae.jpeg7D1466AA-3B93-4720-8881-818A31F3050A.jpeg.e4576d8f8a3d2ec269bb8b19356a5e67.jpeg56EF8579-F33D-4C4B-8737-E1AA5E7DBB20.jpeg.bfe74c2cd6d2788e379f36d414c6efaf.jpeg879CF935-9377-4791-9033-347D72A82B61.jpeg.ea1917ff70d984fba762f74eeb7866ce.jpeg

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      True. My statement needs qualification. "For a shade tree mechanic, re-assembling the front engine to achieve a rough baseline timing of 0 degrees, as is approximated and indicated by common visual indicator mark alignment, measured with a human eye capable of 20/20 vision *with correction, I am reasonably confident that I have followed the outlined procedures/ prescribed methods for verifying baseline timing."   😉   In the end, the computer sets the timing, it's continuously variable based on sensor input, and the distributor only has a degree or two of physical adjustability intended for dialing in the final setting for cam ****** once everything is back together. But even that final value is acceptable within, I believe, +/- 3 degrees.   I thought my exhaust project was going to be a bear. To my surprise, the old clamps came right off last night, and I was able to unbolt all the hangers instead of having to muscle the rubber mounts. The old cat is ready to slip off the factory y-pipe. The rest is ready to come out with one or two cuts, and I've got a fresh blade waiting. I love living where rust isn't a thing.

      PF63 Oil Filters Going Away?

      I work at a Chevrolet dealership & hear it all believe me.  Just reads like there's going to be a fist fight over filters.  Can't get enough, continue!!

      Tire psi

      By Chuck FB · Posted

      I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ).

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol
