I changed out the stock HU on my Mazda Mpv. I used the wire harness adapter and all went well. But I have no dash lights now. I have checked all of the fuses that I can find. I have also put old HU back in to see if there was a problem with my wiring still no lights. I removed the instrument cluster to check the lights and they are all good. The strange thing is I have power on both sides of the place where you install the lights. There is no ground? On the harness there is a orange wire marked dash illumination but no orange wire on the HU. How do I get my dash lights back? Any help?
