a/c lighting
 

Hi all.
Further to a recent post of mine regarding a crappy radio install by the previous owner,i bought a reverse wiring harness and managed to re-connect the factory radio which now works! The problem is my a/c panel only lights up when the headlights are off!! it all works fine but when I put the headlights on the lcd panel goes dark, still works but goes dark, also the gear indicators by the shifter are not lit up, but I don't know if they are supposed to illuminate??? did I mess the wiring up or miss one?
