Ok there looks like there are far too many wires there lol. Try the red ones to + and ignition on the new loom. Black one to negative. Orange one to Illumination.
Then if that doesnt work try unplugging the red one on the new loom and pluging it into the yellow. Then report back. Try taking a picture in the light, the sensor on your phone will get a much better pic lol.
Sorry i cant be much use, i really havnt played with any head units for a long time. I need to do more and refresh my memory.
