Looking to put an aftermarket Led Light Bar on the roll bar of my 2016 All Terrain X. Has anyone attempted this yet? I noticed the roll bar is wired from the factory for the GM accessory off road lights. Looking to see if anyone knows what fuse I should tap into and what wire for the fuse, assuming its already wired to a relay. Thoughts??

LED lights should be find to splice into the wiring. I am unfamiliar with how the terrain x is wired and where the switch for those lights are. But id be shocked if the wiring couldn't handle the light bar. It would be pretty easy to test, and worst case scenario you can just use the factory wiring to see where to run the wires for the light bar.

Planning on using the factory wiring, I can trace it to the relay and battery, just cant figure out where it goes from the relay to the cab???

Hoping someone may know.

Are you planning on keep factory lights, plus a light bar? If so, just tap into the wires on the roll bar, then wiring is simple and easy and 1 switch turns on everything. If youre getting rid of factory lights, then just splice the light bar wires to factory wires and again your done. I dont understand why you need to check fuses and everything else.

Could be wrong but I think he is saying he has no lights up there and just believes the wires are waiting.

 

I am unfamiliar but GM seems to have a trend this year that they are not p reinstalling any unnecessary hardware. examples include) The missing second battery tray and possibly the wires for LED box lighting are not present. There is an outside chance there is no factory lighting unless the factory lights were actually installed.

A little off-topic, but does the high-mount brake light on your cab light up when you hit the brakes? I was thinking about getting an A/T X and removing the roll bar and wanted to know if the light up there still works or if it's disabled in the BCM. (I'm assuming your roll bar came as part of the normal ATX package from the factory).

Yes didn't get the factory off road lights. They're a grand for those 2 small lights.

The bar is part of the package and yes the third brake light in the bar works, however the third brake light on the cab is disabled because of the bar. It does still illuminate when you turn the box lights on.

Talked with a tech, the wiring runs through the ecu so it's possible to do but certain pins need to be moved around and then the truck would need to be tree programmed to accept those pins.

Seems odd that it would come from the factory with the bar but not be wired to add the lights easily. I could understand more if you got the bar added on after the truck were built.

 

Did the tech say whether you can re-enable the cab brake light? I see deals all around me for a new All Terrain X but I would want to pull off that bar and have a normal brake light function.

Is there any more info available on getting the cab mounted brake light to work when removing the light bar. I just bought an all terrain sierra and the first thing I did was remove the light bar/ roll bar. I never gave the brake light a thought until after I had removed it.

Define super cheap. Make me an offer. I have no use for this aside from keeping it for the next guy.

Picked mine up off of amazon for $90, can't remember the exact size 40" to 44", but it's 540W and 48000 lumen. The included wiring kit wasn't long enough so I had to rig up my own. Unfortunately I can't upload a pic as the file size is to large.

Do you have a link to the Light bar that you picked up? I would like to add one to my All-Terrain Bar.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
