Hi All,  I am looking to install a factory video screen mirror and camera into my 2020 Sierra 2 door WT. As it’s a WT I do not believe it has the wiring harness that all other models do. 
 

Does anyone have a schematic for the 4 pins in the connector. Also if it helps wire colors are RED/BLACK/GREY/GREEN.

If I’m reading this schematic correctly, what do the following wires control?

 

Pin 8 & 9.  Are these for the drivers side mirror only?

 

Pin 1. Backup lamp control.  Is this tied into the reverse lights and if so what function does it serve for the mirror?

Does the WT even have the camera system?

 

Just a guess, but when you reverse, the camera view is displayed on the radio (maybe it then doesn't display on the mirror).  Also, I think those mirrors have auto dimming, so it could disable dimming.

 

In any case, I'm sure someone can actually help.

The WT has a backup camera system that interfaces with the IOR radio.
 

This is the video display mirror rear that is tied into the 3rd break light camera like on the Denali’s. I have all the parts including the cabling, mirror and camera, I just need the wiring requirements to install. 
 

WT’s do not come with an auto dimming mirror but the HD Video Mirror has a dimming sensor on the back of the mirror for the mirror and it ties into the auto dimming drivers side mirror if you have it (which WT’s do not).

 Are you trying to create and adapter for the WT that only has the one plug shown below? The is a picture of the plug in my 2021 Silverado WT

 

If so, I am very interested if you are able to create and adapter to make this work.

I’m on mobile right now but gmupfitter should have what you’re looking for for identifying.

If I’m understanding the situation correctly, the WT doesn’t have the full x1 plug up top.

Based on the schematic I pulled up the DD8 wiring is probably whats available. DRZ being the rear cam. There is no red identified so that plug may be for something different under there. Possibly a rooftop beacon for the WT? If the full x1 is up there you should be able to tap into those pretty easily.

      The Peckish Synapse

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.

      New Duramax rumor?

      New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.

      first oil change - 2026 2500HD gas

      I am not a NOCO fan for a charger I would leave on a battery 24/7. The reason is, it doesn't really float. It waits until the battery drops to a certain voltage and then charges it back up to 14V. It's better than no charger I guess.

      I would never do anything but lithium.   If the vehicle is stored, just turn the disconnect off. My batteries are completely disconnected form everything in the trailer when my disconnect is off. Trailers don't always come that way as some still keep the CO/LPG monitor on. When mine is off...it is off.   As far as storage temps, LiFePO4 are good down to -20°C. I would store them in a heated place if it goes below that. You can also get heating mats with a thermostat if power is available.   The way the heaters work, if it's below 0°C, if a charge comes in, it is directed entirely to the heater until the battery gets above 0°C and then it allows the charge to go to the battery.   For my Android tablet I use as a display, I can move it inside my house if I was ever in an area that got super cold.
