First, GM has made it so it is difficult for non-GM software to be installed on their computers, or to modify the GM software that's already installed.  In the past, GM has permitted people to upgrade the software in their trucks, for a fee, to enable various things that were available for the truck, but weren't installed on the truck when it was built.

 

More recently, GM has limited what changes to the truck's software they will permit to be made after the truck has been built.

 

This happens to be one of the things GM won't permit being installed in trucks retroactively.

We went looking for new 2019’s but we’re told because of the strike last year, there was no inventory of them...so we looked at the 2020...We asked our salesman if the mirrors pulled out for trailering, if it had a trailer brake controller and because the window was tinted, I could not read the sticker and wanted to know the size of the engine...his response was, no, the mirrors don’t pull out (they do) the trailer brake was the knob with the trailer on it (after getting the truck home I found out this knob is for the transmission) and he said the engine was a 6.2 gas, which turned out to be a 6.6 gas...I did not know about the engine because I was more concerned with the trailer brake, which I need for towing...after some haggling, they said they will install an after market brake but I wanted the in dash type...took them about a week to get it in and they sent it out to be installed...took a full day...drove the truck for one day and it started to get stuck in park...took it back; they tried all day and it never had a problem but they wanted to keep it overnight and try it in the morning...it wouldn’t come out of park...they said the part would take a week to arrive...after not being called after a week, I called them and they said the part is back ordered and maybe I should try calling GM, which we did...they were not happy...so after two weeks, we got our truck back...tried to tow this morning and the trailer brake doesn’t work...checked fuses, connections, battery...that’s when my wife found your site...first thing tomorrow morning we’re contacting a lawyer...life long Chevy people and today that’s come to an end...

 

Sounds like you should’ve shopped around longer for a truck that had the options you wanted.

At the end of the day, the onus is on the purchaser to do the research and know exactly what they are shopping for & what they are buying.

If you have a 6.6, you have a 3/4 ton or one ton.  You're in the half ton forum.

Sounds like you can’t read...you’d probably be a great salesman for GM...

I read your word wall just fine. It’s not GMs fault that, based on the questions you’re asking, you were an uneducated buyer.

 

You also settled for aftermarket parts. So again, not GMs fault.

I recently traded in my 2017 Sierra Denali for a 2020 Sierra Elevation that didnt have the factory brake controller. After some research, and my dealer's recommendation, I ended up putting in a Curt Spectrum controller, C51170.

The brain mounts hidden underneath and it has a knob that can be mounted wherever you want. I chose a spot to the lower left of the steering wheel so only I can see it but still have easy access. It's as close to an OEM look as you're going to get while still having an excellent brake controller.

It is also super easy to install as its completely plug-n-play with the purchase of the OEM connector, C51525. It took me longer to tie wrap the wiring to make everything look nice and clean than it did to install the brain and the knob.

etrailer.com sells the package together in the link below.

Hope this helps!

By “factory unit”, you mean the Curt unit?

OH!   OK.  This is not the one I say is "Factory"  This unit is not integrated into the DIC, but is a good alternative option that fits in the factory location.

It's a very good controller and the one I have too. See my post above on this.

I opted to install it to the lower left of my steering wheel so it's out of sight. The blue lights are bright and somewhat annoying located out in the open like in your pic, just FYI. Lots of reviewers have stated this and I'm glad I listened to them. Either way, stay safe out there and avoid the Corona! LOL

I just ordered the Spectrum but also read that you can control the brightness. I was planning to install it like the pic. Is that not the case?c4189aaa3661cb8440a78328e62cac68.jpg

Ok thanks for the heads up. I guess I’ll try it out and see and worst case buy another plastic cover if it’s too bright. Also, are the lights always on even if you’re not using it?

      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

      I'd guess that it's because they are Mann-Hummel filters since about 2016, they own Wix and are mostly all made in China now.
