Ok, I have the SIRIUS turner for my D3 I was wanting to know what you guys plug the power lead into? Do you splice it into the power for the D3? Or run a whole new line to the batt? Also same for the backup cam.

either the d3 or the ignition i usually run power the shortest distance possible so if your module is near the d3 go there if ur closer to the ignition go there.

Make things simple, pull it from the radio.
