Customers that upgraded to the Sync 4 from a Sync 3 and have 360 camera will be utilizing an additional section of the included harness.
This additional section consists of a blue wire with a posi-tap, and a red wire with a posi-tap. Both of these posi-taps will need to be attached to the respective wires that are part of the factory wiring connection to the module called the IPMB (Image Processing Module B). For vehicles that have 360 Camera, the IPMB will be located right behind the radio screen in the dash cavity.
There is a rectangular connector attached to the IPMB that the two wires will positap to. Actual photo of the IPMB is further down near the posi-tap instructions. When unplugged, it looks like this.
The wires will be at pin cavities 5 and 15. Pin 5's wire is a green with an orange stripe, blue wire from the harness will posi-tap to that wire. Pin 15 is a gray wire with a blue stripe (right below pin 5 that was just posi-tapped to) and the red wire will posi-tap there.
Note: The connector picture below is how the connecter would have wires in it if you unplugged it and were looking at the part that plugs to the radio. If looking at the wires going into the connector while currently plugged to the IPMB, the image below is reversed of what is being looked at. So pin 6 (visually) would actually be pin 5 in reality. This is why pin 5 visually is vacant, because pin 6 is the one that is in fact vacant.
This is what it looks like while plugged into the module. It's noticed that this view is reversed of the above information due to which direction you look at the connector. Blue line references the posi-tap for pin 5 (Green wire with an Orange Stripe) and Red line references the posi-tap for pin 15 (harder to see with pin 5's wire in the way, but it should be a Gray Wire with a Blue Stripe).
Simply unscrew the gray connection on the posi-tap, and then slide the corresponding wire into the groove of the pink end where the gray cap was removed. Then screw the gray cap back into place until secure.
