Coleman Airxcel thermostat and controller box installation

[tuseggrolls]

I did search, but I still need help to figure out what I did wrong, or probably, I didn't know enough. It has been a week of trying.

I want to replace the mechanical manual control knobs of the Coleman Airxcel Mach 3 Plus to a Coleman Airxcel 8330-3862 T-Stat Wall Digital Heat/Cool, and also replace the control box with the Coleman 9330C755 Control Box.

My problem: I could not find how to power the thermostat, as there is no +_12VDC in the current set up, only a -12vdc.

Any information of how to do the wiring would be appreciated.
Please help
Nick

I do have the manuals of both units, but no mention of how to wire the red cable (+12vdc) to power the thermostat.
