I have a 04 jeep grand cherokee special edition and the factory harness was cut out so I figured whatever I'll just hard wire it. Found all the speaker wire colors matches them up but the battery wires which I assumed were the two red and white ones don't have power running to them but the two black ones do. I thought those were the ground. The illumination has constant power. So, I hooked them up with the black to battery since it's constant and the red and white to ground but it keeps popping the fuse in the back of the radio. Am I missing something ? I can't find and diagrams or forums with this issue. Please help !!!
