Trouble Removing 2019 Sierra Multifunction Tailgate & Wiring

Hey y'all! First post here in the forums. Nice to meet you! I have a 2 week old truck - a 2019 GMC Sierra SLT 2WD w/premium plus package. Same overall as my '16 GMC Sierra SLT 2WD I traded in, except I really like the moonroof and the rear seat air vents!

 

I purchased an OPT7 Redline tailgate LED light bar and am installing it. It's wired correctly (directly to the tail lights to avoid blindspot/trailering/backup/crosstraffic issues)… I took the spare tire out first and did the wiring and tested everything.

 

I now need to remove the Multifunction tailgate to better prep the paint and adhere the lightbar to the truck. I've disconnected one of the two fabric-loom-covered wires easily... the other is a HUGE wiring connect unlike any I'd ever seen and I really can't figure out how to unclip it.

 

Have any of y'all disconnected the wiring for the Multifunction tailgate successfully?

 

Thanks!

Looks like in the bottom picture, the black tab needs to be depressed, and then the white "keeper" needs to be pulled back/rotated away from the loom.

Got it. There was a red tab (like many wiring connectors) hidden above that wiring contraption... seriously would be impossible for anyone to see with their own eyes... only saw it from a picture I took from above the connector. Pulled that red tab up toward the sky, pressed the black tab (below the gray hinge thing) inward... and the gray hinge thing folded down easily and the whole plug came out without issue.

 

Removing that tailgate was a major PITA... it doesn't have quick-disconnect support cables on each side (connecting the tailgate to the bed) like every truck ever made. A 1/2" socket on a drill was needed. Then (as another thread re: removing the entire tailgate here mentions), you really gotta tug on the passenger side hinge at a 45-degree angle... and keep tugging until it pops out. I'm glad the whole unit is built tough but damn. 4+ hours to install a tailgate LED bar. 30 minutes for wiring/soldering/electrical tape... 3 hours for that damned tailgate... and 30 minutes for lunch. :D

 

Here's the light bar I chose to install... looks fantastic:

Any tricks to getting the tailback back ON?! My passenger side popped off and I can't seem to get it attached.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
