Speaker Wire Breakout Harness IOB

This harness is for those adding an aftermarket amplifier to their 2016-2018 Full size GM truck, and do not want to cut any of the factory wires.  This harness will simply separate the 4 speakers, outgoing signal, from the radio, and the return signal to the speakers.  Leads on harness 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 inch screen IOB radio without the factory amplifier, speakers codes UQA or UQ3.  Please contact us prior to ordering if unsure on your trucks stereo system.  Also please provide your vin# when ordering as we will confirm fitment for you.
