Hello all, installing this stereo http://www.pyleaudio.com/sku/PLDNV78...nd-Mexico-Maps

It's got built in steering wheel control. I just need to know which wire is the main steering wheel control wire. I uploaded a pic of the wiring diagram fir the radio.

Thanks

 

There's two signal wires from the car, and your headunit only has one signal wire input. From the amazon and sonicelectronix reviews, nobody's figured it out:

But, I'd guess that if you used a resistor on the wires (the way the PAC SWI unit differentiates the two wires into one) it'll work fine.

Connect the yellow wire from the vehicle's harness pictured below to the Pyle's SW KEY GND (gray) wire, the green wire connects to Pyle's SW KEY (green) wire through a 150 ohm resistor, and the red wire also connects to the Pyle's SW KEY (green) wire without a resistor.
