UPDATE AS OF 08/02/23. PARTS HAVE BEEN RELEASED TO US AND ARE IN TRANSIT FROM OVERSEAS. PRODUCT WILL BE AVAILABLE BY END OF AUGUST. ONCE PARTS ARRIVE WE WILL RELEASE AND ALLOW ORDERS TO BE MADE. This harness is for those adding an aftermarket amplifier to their 2019-2023 Sierra or Silverado, This harness breaks out all the speaker signals from the radio and back to the speakers. It also has a lead for constant power and ground. Wires are 6" long which allows you to add on your own wire to and from the amp. This is only for those that have the 7" screen or the 8 inch screen without the factory amplifier, speakers codes U95/UQF. Please contact us prior to ordering if unsure on your stereo system. Also please provide your vin# when ordering as we will confirm fitment for you. With this harness installed and no amp added, there will be no sound from the speakers at all as this harness completely separates the circuit, it is not a pass through. If you wanted to have them as a pass through, you would just simply connect the ends together.
