Has anyone successfully added the qt6 power up and down to their Silverado custom trail boss

[Julio13]

I’ve checked on gm parts website and they sell a module just for that option qt6 tailgate I wonder what else would be needed to add the power up and down option?

i am doing this within next week.  i have rst with power down gate.  i am going to try QT6 i have all parts, just need time.  you need new torque rod, new right side hinge gateside, new right side hinge body side, module, harness, left latch, right latch and motor.  I found some parts at nordstroms and some on lookupgmparts.com I will do a write up if it works.

Awesome would appreciate it around how much will it cost total if you don’t mind me asking

Simple, going to have to program the BCM to tell it to bring the tailgate back up.

Tag for updates

in closed position, if i hit handle button it beeps.  i think the qt6 tailgate is supposed to beep in down position. right now i think in up position it thinks it is down.  maybe i need to take out motor and spin motor 90 degrees?

i have succesfully added memory seats without programming so i was hopefull this would work too.

Were you able to get this working? 

[Rally6.2RST]

right now tailgate will drop smoothly with push of handle button.  I think I have a bad right side latch. the latch doesnt lock correctly.   I ordered a new one and am waiting for it to arrive.  I think sensors in lock are causing module to limit function.

[Rally6.2RST]

I finally got a new right side latch.  This did not fix the issue.  I think I am going to give up and send these parts back to salvage yard unless anyone else has ideas.  Maybe @GTPprix can solve.

i figured out the interior dash button for tailgate is different between a qt5 and qt6.  I switched this switch out. now tailgate worked up and down with interior switch, tailgate switch but not working with the key fob.

I got everything working for QT6 like factory.

 

To upgrade from at QT5 (originally I had version with one lock actuator there is a QT5 version with 2 lock actuators)

You need new torque rod 84536703 ($20),  new right hinge gate side and body side 23388858 ($30) and 23388847($30),  lock regulator right 84533175 ($65), lock regulator left 84533174 ($65),  module 84652297 ($100 got mine used for $40 a new one would probably require programming),  harness 84682842 ($75 I got a used one for $40), switch for dash 84482867 ($15), motor 84490334 ($200 got mine used for $100)

 

Before you remove torx bolts on right side body hinge you need to remove the right side taillight and remove the 15mm bolt holding the soft open spring.

 

You may have to dremel a plastic key tab on male fakra connector for camera wire to allow it to plug in at body harness

 

You may have to drill out some holes in the mounting plate on bottom of tailgate for actuator 

 

With all of these items installed you will have up/down use of interior switch and exterior switch but not key fob.

 

To get key fob to work you can do this.  There are probably better ways.

I was able to get key fob to work I removed the green and yellow/black wire and plug from my old harness QT5 harness and added them to my QT6 harness to power the old QT5 actuator (these wires come from BCM).  I turned my old actuator into a switch by sodering a wire to the actuator cam and sodered a wire to the latch bump  I ran these wires to exterior switch so when I activate fob the actuator spins and connects the circuits and complete exterior switch circuit.

I too have followed what Rally6.2RST has done and have gotten the QT6 Tailgate working almost like factory, the only difference is the key fob just requires a double tap to bring it up and/or down rather than the press and hold like factory to bring it back up.

 

I also did not use P/N: 84652297 for the tailgate module, I instead used P/N: 84651736. I originally ordered the 84652297 but did not think it would require programming (it does). I then found this tailgate module (84651736) that looked the same and had the same number of pins and the same placement of pins. I ordered this used part not knowing if it was gonna work or not. I received the part this morning and it worked.

 

I did use Rally6.2RST's method of the tailgate control signal for the key fob by using the old harness pins (as seen in the pictures below) However instead of using the old actuator as a sort of diy solenoid switch I just used a regular relay and soldered the wires directly to the new harness. I didn't want to completely tear apart both harnesses and redo them into one, but I also didn't want to just solder two wires and let them be exposed throughout, so I taped and zip tied both harnesses together all the way through and only used the two pins I would need for the old actuator/ new relay signal. and kept the other wires tucked incase of future mods I have those wires already running through the old harness.

what are specs on relay?  where did you get yours?  I know nothing about them.  I want to do the relay way instead of using old actuator.  what i did was kinda ghetto but i had to work with my limit knowledge and was really trying to get fob to work.
