Head unit & steering wheel controls?

Installing a new non-OEM head unit and failing to retain the steering wheel controls?

I see these 5 wires that were plugged into the OEM unit.

Does anyone know which ones enable the steering wheel controls?
Is there a harness I can get to connect the right wires?

Here's a snapshot of the back of the OEM unit at the top, and the new touchscreen head unit below.

Can anyone help?!

 

Not sure what brand of head unit you have, but you could try this place.

 

Use an interface for that. PAC or iDatalink.

 

Crutchfield has all the install instructions and connector diagrams.

 

Did you buy the Metra harness with the head unit? typically should come with everything you need. As mentioned above check out Crutchfield.

 

welcome

 

I installed this head unit...

 

And bought this harness to help w the install...

 

...but it didn't work.

I have now returned it and am using a bluetooth cigarette lighter dongle that is remarkable effective...

 

China unit, that's why it didn't work.
