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

That crimp tool will work, you might need to finesse the edges of the crimp to make them conform to the cavity but they’ll get it done. Bummer about the color but I’m sure you’ll find a buyer. Also I’m pretty sure @pgamboa can send you a harness cheaper and faster than buying the tool, wire, tape and terminals...etc Also I haven’t seen a Silverado or Sierra with anything but JST connectors, the written instructions are for a Canyon/Colorado.

@TinkeringFox I've seen the same thing with the connectors on the suv plaform...all JST at the BCM.

I ordered the old blue # 23317218 online from gmpartsoutlet.net for $42.47 with shipping. Works perfectly!!

I'd really like to thank TinkeringFox for the awesome video and information. Have everything installed and functioning beautifully. 36,000 lumens on that light bar. I had purchased the OEM Sierra's RED switch by jumping the gun , but I actually think the Blue & Red match the instruments cluster pretty well. I'll take some pictures of the buttons illuminated later and where I installed my relay. I had a slightly different install.

I hit a problem with my 2019 Silverado 2500. I had my lightbar installed and running prior to soldering in Pgamboas harness.

I plugged in his harness to the appropriate plugs, changed the OEM light switch, soldered it to the trigger wire, I even used the same ground and power locations, bolted the relay to the same spot too. But unfortunately the light bar doesn’t turn on with the factory switch. 

Do I have to get the ECM flashed or is it just not possible on my truck? JST and Delphi plugs just like in tinkeringfoxs video. 

Everything seems very straightforward and i’m 99% positive i’m in the correct pin locations, orientated correctly and pushed in far enough. I bought and replaced the relay that didn’t change anything, fuse is good going to the light bar and my ground location is good. 

Any help would be greatly appreciated.

Check to see if you have power coming out of the switch. Then ohm the wires out. It was my luck, there was a break in my yellow wire somewhere. I replaced tha wire, all good.

In my case, yes, it was just a broken wire. Mine is a 14, so it wasnt able to be wired to my bcm. 

 

I would still take a test light and see if you have power coming out of the switch. Also, dont you have to do a long press of the button?

I’ve held it for 5-10 seconds at a time and not a thing. No click from the relay no lights on the dash or from the lightbar. Will have to go find a meter and check this out thank you.

A simple test light will check to see if you are even getting the signal out of the switch.

      Video processing module location

      By twgraham · Posted

      Can someone tell me where the video processing module is in a 2023 Silverado? I'm getting conflicting results that it's in the front passenger area or the rear passenger area behind the seat.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.
