Im pretty decent when it comes to electrical but WTF?  LOL. I know it easier than it appears but still.....

I think the factory switch puts out a momentary positive pulse. 

 

Yeah.... im lost now....

I'm still having issues after installing my new switch and wiring harness, my ORL light in the cluster does not come on or no voltage is being outputted from the switch.  The other day I acquired a latching relay, with it connected to the BCM, the switch does not operate and stay on..  I disconnected the BCM terminals from the wiring harness, the switch works great.  No ORL at all on the dash, but the ORL indicator in the switch lights up.   I have a 2018 GMC Sierra 2500HD SLT, has anyone else had this issue?

Care to share where you got your relay? The light turns on AND off? Is it a long push or a quick push?

Waiting for Seapacer2 to put up the link for the latching relay and see if that works for us 2014 truck guys.

I got my latching relay from Amazon,

Pay close attention to your jumpers,  I had to move them to get it to work, this latching relay works great.

Yes, you hold the ORL button down for a few seconds, it turns on.  Push button again to turn off.

 

i have attached a photo of the 4 channel relay, disregard the wiring color, I utilized what ever I had in my tool box to test the operability of the system.

Awesome!!! I hope it works. For us guys with the 14 and 15 trucks, i think this is pretty much last resort besides for using an aftermarket switch. Thanks.....

Last thing.. can you take a close up of the wiring on the top side of the relay..  is there directions in the box?

All,

This is the same latching relay (there is a 4-channel and 6-channel version) that@Tinkeringfox and I are testing (mainly Tinkering Fox [emoji4]). He will be releasing a video on its use soon. For those that are familiar with wiring it up can get the relay and do their own wiring. For those that are not that saavy, we’ll be designing a “kit” for it. The good news is that this relay can also be used in conjunction with the Instrument Panel switches that also send momentary triggers [emoji6]. Please be patient as we are both very busy with work.

Stay tuned.

Is this 14 and 15 specific? I’m working on a project for a light bar on my 2018. Will the ORL switch work with your harness Phil?

    • 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    
    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
    • This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.  
    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
