2014-2018 Chevrolet Silverado/GMC sierra AMP Install w/out 7' screen

In this video we go over the installation of the LLJ Customs factory amp bypass T-harness 1418SAB. This harness will plug and play into the radio unit along with a PAC LP7-2 high level to low level Line output converter to install an aftermarket amplifier! this harness does not support GM or GMC vehicles with the 7" screen that is a different harness.

-What the LOC LP does is take the signal from the radio and turn it into a low level signal for your new amp to use, this is only for use with a mono amp.

With 8 Inch screen:

With Bose:
