Okay, here is a solution to those that wish to use an aftermarket head unit on their Aurion buy don't want to buy an control box to get their audio controls working but still want to retain DISP button functionality.
You just need to ground the pink wire on the steering wheel control harness.
Thanks Mikeyboy for taking the time to help out. I just wasn't willing to ground anything on that harness without knowing how it integrates at the other side. It's just because the DISP button was tied into it that I thought something isn't quite normal.Please wait a few seconds for Video to Load!
Just for you, I took my head unit out and took some measurements. When you look at the car side of the wiring harness you will see three connectors. The following is in reference to it when you are looking into the socket of the plug itself. Using the colours you can reference them. For the stereo, you will only need connectors 1 and 2. If you want to integrate the steering wheel buttons through the use of an external controller, then connector 3 has been included for reference. Only the wires present have been included:
Connector 1:
1 - Light Green - Speaker: Front Right Positive (+)
2 - Pink - Speaker: Front Left Positive (+)
3 - Grey - +12v ACC
4 - Blue/Yellow - +12v Constant
5 - Blue - Speaker: Front Right Negative (-)
6 - Purple - Speaker: Front Left Negative (-)
7 - Brown - Ground
8 - Orange - Antenna Power (+12v to power antenna amplifier)
10 - Dark Green - Illumination (+12v when tail lights on)
Connector 2:
1 - Red - Speaker: Rear Right Positive (+)
2 - Black - Speaker Rear Left Positive (+)
3 - White - Speaker: Rear Right Negative (-)
6 - Yellow - Speaker Rear Left Negative (-)
Connector 3:
3 - Purple - Speed signal (used for ASL in stock unit)
6 - Pink - Steering control ground
7 - Orange - Steering control signal (for SEEK and VOL)
8 - Yellow - Steering control signal (for MODE)
Don't be fooled by connector 2. It may have thicker gauge wire and have Red, Black, and Yellow wires which are commonly used to power a head unit, but these are speaker connections only.
I hope that helps for now, and good luck.
