Replacing entertainment head unit - different wiring harness
Hello,
In my 2017 Roo, I am replacing an iRV31 head unit with a new iRV 31 head unit. The wiring harnesses on the new unit are different. For the power (A1-4 on the right), I am not sure how to proceed.
The old unit has:
A1 red (12V Pwr)
A2 black (GND)
A3 N/C
A4 N/C
The new unit has:
A1 YLW (BAT)
A2 Black (GND)
A3 Red (ACC)
A4 Blue (ANT PWR OUT)
With the new harness I ran A1 to where the previous was connected and A2 to GND. But nothing happens when turn battery power on. Since there was no A3/A4 on the old connector, where do I connect the new unit A3/A4 to? The same as A1? Images attached.
