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.

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.

      They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years
