BraddB Posted January 24 Report Share Posted January 24 I recently installed an aftermarket Android head unit in my car and it a;llows you to use your factory steering wheel controls, but to do this there are two wires on the head unit that are Key 1 and Key 2. These two wires need to be connected up to the factory wiring harness on the main plug. Can anyone point me in the right direction as to which these two wires might be? Thank you.

BraddB Posted January 25 Author Report Share Posted January 25 (edited) Nobody has any ideas? I have searched and searched all over and can't seem to find a diagram or picture that shows me what two wires I need to connect. Any ideas or help would be GREATLY appreciated. Thanks Edited January 25 by BraddB Quote Link to comment Share on other sites More sharing options...
MLTEdge Posted January 25 Report Share Posted January 25 Maybe contact the head manufacturer to ask them? They must have a clue where to start, or how to test wiring to find correct ones. 2 Quote Link to comment Share on other sites More sharing options...

I thought about this too, but the Ebay seller either doesn't have that info or just doesn't want to give me that info. I know what wires to use on the head unit, just not what wires to connect them to on the factory wiring harness on the edge. I can't find any info anywhere that tells me what wires going into the harness are for the steering wheel controls. I do appreciate your reply. Thank you.

1004ron Posted January 25 Report Share Posted January 25 (edited) One of the downsides buying too cheap. Crutchfield prices are very competitive and tech support cannot be beat. You will probably need an adapter like the ones in the below link, but which ones will depend on your vehicle model and the 3rd party head unit. https://www.crutchfield.com/shopsearch/steering_wheel_control_adapter.html https://www.crutchfield.com/g_751/Factory-System-Adapters.html Edited January 25 by 1004ron 1 Quote Link to comment Share on other sites More sharing options...
BraddB Posted January 26 Author Report Share Posted January 26 Looks like I need to do some reasearch and figure things out. I had to do this about 10 years ago when I added an aftermarket head unti in my Escalade, but it was a name brand stereo, not some generic Android unit.

Haz Posted January 26 Report Share Posted January 26 Based upon this description from the 2013 Edge Workshop Manual... Steering Wheel Controls The steering wheel controls are mounted directly to the steering wheel and wired to the Steering Column Control Module (SCCM) . Depending on what features the vehicle is equipped with, the SCCM sends messages via the High Speed Controller Area Network (HS-CAN) to the PCM (cruise control) and the Instrument Panel Cluster (IPC) (message center and entertainment system). The IPC receives the SCCM entertainment system messages via the HS-CAN and then sends them to the applicable entertainment system module(s) along the Infotainment Controller Area Network (I-CAN) . ...and this Front Control/Display Interface Module (FCDIM) - wiring diagram... Your Edge's main plug may be the FCDIM Connector C2123... If so, then your Aftermarket Head's two wires may find their rightful places on Pin 4 and Pin 5...

I gave that a shot, but it didn't work. Although when I connected those wires to the head unit and attempted the steering learn function it said it was sucessful but it wasn't. It looks like even though I shouldn't need one of those boxes I will have to buy one. The only thing I wanted it for was the factory voice commands. The fatory mic works so much better than the aftermarket mic. Edited January 28 by 1004ron Really no need to quote it ALL Quote Link to comment Share on other sites More sharing options...
1004ron Posted January 28 Report Share Posted January 28 Getting the steering buttons interface working isn't necessarily going to help with the mic. Quote Link to comment Share on other sites More sharing options...
