I have all the connections figured out, except for the steering wheel controls. Can you provide guidance on what to connect? Do I need to tie the key1&2 wires to the 3.5mm jack? Is the extra black wire part of the steering wheel control wiring and need to be grounded out??
This is the connectors on my truck:

Also, I am frequently towing and would like to use the back up camera to check on the trailer while driving forward. I rigged the camera so that it has power whenever the radio has power. Is there a way I can access the reverse camera app without the car being in reverse?
