I just switched out an old JVC with a new Dual. I swapped the wires exactly as the old one was set up, color to color, & I get no power. All that is left are 2 orange cords, an Illumination & Positive Dimmer, I swapped some cords around, that being using the orange ones, and I get power, but next day, no power once again.. I never got the memory working, when I did have power, should just be yellow to yellow.. Idk its a 98 pontiac, thing already has horrible electrical problems, but the fuses look fine, and the old deck, set up color to color, worked just fine... Any ideas would be greatly appreciated!
