This harness is for installing your radar detector into your 2014, 1500 model or 2015-2018 and 2019 old body style Chevrolet Silverado.  This harness saves you from splicing and/or entering pins into your trucks wiring harness. 

There are 2 different connection points for this harness.  If you have a manual dimming rear-view mirror the connection will be at the fuse block.  If you have an auto-dimming mirror it will connect inline with your mirror harness.  A manual dim mirror will have a flip lever on the bottom side that is used to dim the mirror.  An auto dim mirror will not have a lever on the bottom. 

This harness is for all radar detectors that use a phone cord style connector(RJ11).

Harness also available with a separate power and ground wire for those that may want to add in a dash cam or such.  Please note that these loose leads are an ignition based 12 volt feed and ground.  Most dash cams and such require 5 volts and you will need to make sure and use a voltage converter if needed.  This is not included with this harness.

Works on 2014, 1500 models only
Works on all 2015-2018 GMC Sierra's as well as 2019 old bodies.
