Add USB in Console

[Trey Beck]

So I just bought a 21 RST Silverado and I am missing the USB connections inside the center console. My question is has anyone added this and if so did you have to buy a different wiring harness?  I have been searching the internet for three days straight and I cant find anyone that has done this.  I am a little amazed it is not already there.  Any help would be greatly appreciated.

Welcome to the forum. Do you have the full center console or the center mounted jump seat with the fold up arm rest?

Center console no wireless charger no rear heated seats.  I do have usb in the back seats.

You need to search this forum. Eight or maybe ten guys have tried to add USBs, bought a variety of harnesses, returned them, tried another harness etc. To my knowledge no one has successfully added USBs to a console that didn't come equipped with them. After reading the various postings i decided not to attempt adding USBs to a console that I installed into a 2021 Custom. That said. It may be possible or the radio may not support that functionality.

OK I think I have finally figured out the part needed.  So my truck has harness 84997325. 84997325.jfif

The part needed for the center USB is 84997323.  This harness is for the higher trim. 84997323.jfif

I am in debate whether to order the part and try to add the USB as I do not have the radio with navigation.  I feel like the charger function will work.  If I take the chance and try I will follow up with the final verdict.  (5/8/2025)

Good luck! I hope it works.

The easiest way to do this is to get a 12v to usb converter and wire it straight into the power port on the rear of the console. I think I paid $20 for the converter, and then mounted the ports inside the console. My truck came with the flip up console but I added the console from a 22 high country.  I know that GM sells a Block off plate to take the place of the inside usb ports.   

The wiring harness you're looking at will not give you power or data to the inside ports unless your radio can support it. (the IOR radio will not)
