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.

Free time? Nope, that’s time you’re essentially paying for! Can’t wait to hear the good news....I mean confirmation that I’ll be spending more money on another upgrade!

since I haven't seen a pgamboa video about this subject on YT, I assume it's still a touch further down on the upgrade list..

Yup. WAMS has my cluster and TBCM and CCM. Still trying to get them to communicate.

It seems bizarre to me that GM would make something like this so complicated when an aftermarket box can be added so simply (at the cost of major aesthetic points).

Especially when it seems every vehicle with any of the tow package RPOs appear to have the all the hardware to make it happen.. (save the dash switch).

Yep.  There are 2-3 modules that are specifically for trailer brake.  So those items are omitted...even though some of the dash harnessing is present.

Looks like it can be done now. I'll be trying this out in a month or two.
 

 

This is for a replacement, not adding something that wasn't there before.

Not bizarre, it's INTEGRATED whereas the other ones are not.  One gets features not usually available with an aftermarket controller, especially from 2012 on.

I have a question that I can't seem to find the answer to... My RV that I would be towing does NOT have ABS brakes, but the truck would have (most likely, as I am currently without a truck). 

The question is... would the integrated TBC have any advantage over say an aftermarket TBC if the truck I purchased did not have it installed from the factory?

Yes, check the owner's manual of the truck you're looking at for specifics.  ITBC controls sway and the brakes on the trailer during sway for example.

Gents, at the risk of being sounding dense.  I want to confirm that i cannot just purchase and plug in the new dash piece and controller head?  I bought a tekonsha and was wiring it up and took my dash apart and lo and behold theres the harness for it!  The presense of the harness does not prove that im good to go?

Welcome to the site.

 

No sir, the brake controller is a factory option, and is set up in the ECU, BCM, and so on, it can not be added after the fact.

      Tire psi

      By jgaudet99 · Posted

      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

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

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

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
