Does anyone have access to GM harness schematics? Trying to find the correct harness that goes from the center console to the dash (infotainment system). Installed the center console with storage, cigarette lighters and USB ports and would like to use the factory harness without having to cut and splice. Or does anyone have access to just the plug and I can add my own pins?

This will open a can of worms.  There's over half a dozen numbers, some old numbers that direct to new numbers.  What is needed to help you is to know exactly what you have, and what you're looking for.  The harness you're looking for info on is part of the harness that connects to everything in the center console, including rear seat USB and the key fob reader in the center of the front cup holders.  To get you the right info we will need to know if you have rear heated seats, wireless phone charging, and center console SD card port.

 

Btw, I recently upgraded to wireless phone charging.  My truck had the harness with no rear heated seats, no wireless phone charging, and yes to SD card reader in center console.  If this is what you're looking for, not only could I answer your questions with pics, but I could also sell you the harness.

I'm very interested in the harness you are speaking of. Can you send pics and the cost?

On my 19  the center console USB ports on the rear are powered from the harness under the pass. seat, the electronics inside the console are powered from the USB port on the dash with an extension harness, USB port on the dash needs to be swapped to a different one for the ext. harness to plug into it.

So my truck is a 2020 work truck, no power anything accept for the locks and windows.  7" infotainment code IOR, on the dash below the radio it has a USB and a type c USB(which has the dual mini USB ports on the back and a plug with 3 wires). I installed a center console from an older silverado that has the storage compartment and the arm rest storage compartment, it has a cig lighter on the rear near the floor and one in the arm rest along with a dual USB and headphone(aux in). I also purchased the USB port that has a USB/USB C AND SD card slot on the front and a mini USB and power plug on the back, which I want to install in place of the dual USB/aux in in the arm rest location.

Mine does have the dual mini USB ports on the back which I ran the other port to the other USB module along with power. Doing that shutdown the USB input along with the Bluetooth module. It all stopped working until I disconnected the battery from the truck and let it reset(about 20 min). I put it back to factory and it worked again. Haven't had time to mess with it in a few days....

I have a 2021 Elevation 2WD. and dont have any ports in my center console. Would like to add data ports. Thinking I can somehow splice into the ones up front and make a harness for it for a clean install. Does anyone have information on how I can do this? I want to do it and plug in the usb wireless carplay for a clean look. I know the OEM GM Part number for the console ports is 13529862. I dont know the connector that connects into it.

Do you know the new port numbers and the part number for the harness ext? Trying to add data ports to my center console.

I have a ‘19 Sierra that I added a centre console to from a ‘19 AT4 that had wireless charging and rear seat heat. I harness from the dash to the wireless charging didn’t come with the console so I’m trying to figure out if I get that harness (dash to wireless charging) will that also connect to make the console usb’s work.

Console USBs and wireless charging aren't the same harness.  It doesn't go up into the dash.  There is 1 connection where it does connect to a cable going up into the dash, and that's a mini sd plug, iirc the terminology correctly, to connect the SD card/usb/auxiliary ports that are in the armrest bin of the center console.  The harness is also kind of like a Y formation, where the bottom of the Y is a large plug the connects under the passenger seat.  One branch of the Y ends with the wireless charging and the other branch ends with the rear USB/rear seat heat buttons.

Thanks for the reply!

the console I put in has the wireless charging and rear seat heat. It didn’t come with a harness that connected to the dash.

My jump seat had usb out the back and those work on the new console. My centre stack has the 2 usb’s and the card reader. I want to change that to just 2 usb’s and then what ever harness is required to make the connection to the the console usb, aux port and card reader. Is it possible I have the micro connector you speak of?

thanks, I appreciate your time

I don't know if you can swap that to 2 USBs.  The harness that connects the USB/Aux in the center console is the same one that gives you wireless charging and rear heat.  To swap it you might need to modify the wire harness to accept your change.  I really don't know without looking at the actual pieces.

    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package. 
    • So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.  
    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
