Holden Colorado Head Unit 2017+ - Not Booting UP
80078 is the SKU. Troubleshooting steps for not booting up

There will be two 20-pin plugs that come with the head unit's harness. Only one of them has a pin on pin slot number 14.
To fix the issue, you will have to de-pin PIN 14 and move it to pin slot 15.

How to De-pin Plugs
If you don't have a tool like the one shown in the video, you can get yourself anything thin, and sturdy. Examples include a paperclip, needle, or safety pin. You want something thin enough to slide into the connector alongside the pin.
After that, see if your headunit boots up. If not, give us a email at [email protected] for us to assist further.
Note: We are working already for future harness to be on the right pin ports.
