This past weekend I installed a double-DIN head unit (from Crutchfield) on our 2006 Outback wagon, with a backup camera. The wiring harness from Crutchfield worked fine, and the install went well. However, there were two connectors that were connected to the OEM head unit that had no provision for on the new double-DIN. Other than the Crutchfield connector mated to the white one on the left, there was one attached to a tab (circled in blue) and a multi-pin connector (circled in red) shown in this pic. What are these circled connectors for, and do they need to be connected in some fashion?
