audiofanaticz Posted January 7, 2015 Report Share Posted January 7, 2015 The wiring harness will either be on the steering wheel column or right below the column under the dash. You would need to remove the dash covers that are above your knees below or in front of the column itself. Link to comment Share on other sites More sharing options...
mothra Posted January 7, 2015 Report Share Posted January 7, 2015 Should have just gotten the Axxess GMOS and ASWC, it's plug and play 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...
audiofanaticz Posted January 7, 2015 Report Share Posted January 7, 2015 Should have just gotten the Axxess GMOS and ASWC, it's plug and play No its not.. The module still has to be hard wired to the steering wheel control wires just like the Pac. The only difference with the ASWC is it can automatically program itself, which many times you still need to remap a couple buttons. Link to comment Share on other sites More sharing options...

With this pac module I can plug it into my phone and program it also, change all the functions and add multi function to them also. Makes it pretty simple once I find where to hard wire it lol 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...
RickyFriery97 Posted January 7, 2015 Author Report Share Posted January 7, 2015 I've found the connectors that I think are the ones I'm looking for, but about 6 of them all diffrent colors.. Anyone confirm the color of the C1 connector? 2014 Chevy Silverado Crewcab 1994 Chevy Full Size blazer Link to comment Share on other sites More sharing options...
audiofanaticz Posted January 8, 2015 Report Share Posted January 8, 2015 It should have 14 pins in it, 2 of which are way larger pins. Look at the plug the same way as your image and count the pins, if those same 3 pins have the same 3 color wires in the same location its your plug.If you pull the plug out, there is probably some writing on it, or molded into the plastic C1 which is why they refer to it as C1.
