Once I get home from work, I’ll get OEM part numbers for the modules. Keep in mind that this is not a simple buy a harness and plug and tow. Could you acquire a harness from a salvage yard, yes you could but then you a lot more to sort out cause as with JL1, if you have park assist sensors, the the rear camera, the magnaride suspension and so on, you’d have to get a harness from a truck that has all the same RPO’s as your truck with JL1 cause those wires would for those options would be present in the harness.

I’ll be adding the factory TBS to mine. Once I have the time. Lol. I’ve got the modules ready to go (to get programming done) along with my cluster. There are 2-3 modules, programming, and wiring

From what I've heard, the factory controller can't be added later. Need to look at aftermarket controllers.

Even with adding the additional modules, the switch, the wiring additions (which will be significant and likely insurmountable for those that are thinking just add the switch and go) there is still the programming that will likely be impossible to resolve.

 

To date - this is still IMPOSSIBLE.

TLDR...GM's TSB still applies and it can't be added.  

 

$100-200 aftermarket controller beats the absolute a$$ache you've presented.

No, because GM still doesn't sell the programming update that allows it to work for trucks that didn't come with it from the factory.

More than just programming.

 

Wiring (different chassis harnesses with and without JL1 brake controller), modules, programming.

Sure, but you can add all the physical stuff, wiring, switches, computer, relay, etc, the thing that stops it is the programming.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
