2013 Non JBL No NAV OEM stereo to Android auto head unit harness

What I have been reading is the 3 SWC wires come from this K3 connector. Pins 6,7,8. Should I try to hot wire from K3 pins to pins 8,13,15 here on aftermarket harness?

 

U can try it and see.

 

I can’t seem to find confirmation that those are the correct wires to try but I’m very tempted to give it a go.

 

SUCCESS!
That was exactly it from post #31. However I can only program volume up/down & track +\-. The other buttons on the steering wheel will not link a function. I’m pretty happy with just the 4 and I can program any function to them.

I will add the correct harness links when I order.

Thanks guys!

 

Glad u made good progress. Really frustrating when the seller dont give you the wring stuff and u have to figure it out on your own.

 

Here is what I ended up ordering to keep as much of the factory controls as I could going to an android auto head unit.

U got everything up and running the way you like?

 

I did get everything working. All SWC and OEM usb. Last will be the GPS antenna adaptors.

 

I'm, in the same boat right now.. I have only Volume and track << >> buttons. What did you buy to make all the buttons work?

 

To be clear that was all I was able to program as well with my current setup…still functioning well after 2 years and suits my needs for now.

 

I messaged the seller, they said they will send out the correct harness... We shall see. If I have to settle, thats good enough for me too, but would really like everything to work as intended.

 

Awesome keep us posted on your findings!

 

BTW, any ideas for a more secure fit? I dont feel like the lower part of the unit and the upper part of the HVAC panel are supported at all here.

 

So I got the new harness today and went right to work. All the harnesses connect, but I only have half the buttons on the wheel... I think i need the Non-JBL CanBus harness. Anyone know this part number? It may solve these issues.

 

Harness #3 attempt will be here in a day or 2... Still no luck. Shipping from China takes forever.

 

New harness arrived last night... I went right into it. Now I have Volume +/-, and I have the buttons << >> underneath. But now I lost the phone control, Mode button and voice activate. Not a big deal as I use CarPlay, but still... I have buttons that don't work.
I just received this from the seller. They are asking me to modify the harness like this, in one last ditch effort.

 

You have to be an expert at pulling the dash apart by now!

 

That's for damn sure!!! All worth it... I finally have it!!! all steering wheel controls finally work!!

 

The wire in your harness that plugs into this clip, and this terminal. In the aftermarket harness, there are 2 browns going into this port. cut them from the white plug, but keep them together. They are getting feedback from this wire in the stock harness. Trust me. It was that damn simple!! Hopefully you have this harness.

 

So light brown from the truck - dark brown on the aftermarket harness?

 

Just the dark brown from the aftermarket harness... You can leave the light brown alone from the truck. I was just showing what it was connected to. But yes, disconnect the dark brown from the aftermarket harness. There should be 2 browns in this one pin. Make sure to connect them together, just get them out of the connector.
