RickyFriery97 Posted July 18, 2014 Report Share Posted July 18, 2014 had a buddy of mine bring his 2011 silverado single cab over to get a screen put in. the wiring harness fit, but did not have a chime module(didnt know it was needed if there was no bose / onstar) and i had to tap into a 12v ignition source because the harness did not have one. also when he dims the lights down, the radio cuts off, comes back on when turnd all the way up. figured it was something to do with the illumination. i was just gunna not hook it up whats the correct harness i need to get for him? no bose no onstar 2011 silverado pioneer DD 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...

mothra Posted August 29, 2014 Report Share Posted August 29, 2014 that's the wrong harness you need an interface harness. the harness retains all safety chimes and warning that would normally be done through the OEM radio. the OEM radio also uses CanBus to operate. don't skimp out on using the correct harness. if nothing changes, nothing changes You don't know what you don't know, till you don't know Link to comment Share on other sites More sharing options...

islandpride684 Posted August 29, 2014 Report Share Posted August 29, 2014 You can choose from the OS-4 or the OS-5 from PAC audio, still expensive tho....

TRON Posted August 29, 2014 Report Share Posted August 29, 2014 GMOS-LAN-01 from Metra This. These run about $130, I know it's robbery for a harness but it's the only thing that will work properly.

Stephen13 Posted August 30, 2014 Report Share Posted August 30, 2014 When I had a Pioneer AVH-P4400BH in my '11 Silverado I used the PAC OS-4 and a METRA SW-1. I used the SW-1 instead of PAC's steering wheel adapter on the advice of a car stereo shop owner friend of mine. He told me the PAC unit had "issues" that he didn't like. Later I tried replacing the pair of adapters with a single PAC RP5-GM31 but that didn't work out so great. It worked for about 3 minutes but by the time I got it all installed back into the dash it quit functioning properly so I went back to the OS-4/SW-1 combo. I've since replaced the Pioneer with an ADVENT OGM-1 which doesn't require any 3rd party adapters and IMO is a much higher quality HU. 2011 Chevy Silverado LT 5.3L 4x4 Ext.-cab "Enjoy yourself.
