For factory without navigation, please locate this connector. The perspective of the diagram below is from looking at the metal terminal of the factory connector. Not from the side where the wires are coming out. 

Locate pin 6 and pin 13 on the connector. Connect the airbag light adapter chip's orange wire to terminal 13 and purple wire to terminal 6. We recommend use T tapping to connect to the wires behind. 

The red wire on the adapter chip will need to connect to ACC, which is a red wire on the radio's main harness. Please refer to the pinout diagram at the back of the radio to locate the wire.
