I took out the original stereo, which would power on but get only static. It had no display, which I though was just do to the age of the stereo. I cut the stock harness because I could not find any matching ones at the time (found one now, but too late). I have tried installing 2 different stereos. Both will power on, but neither will actually power up. What I mean, is that there is power coming through (you can load and unload a CD and the red light flashes when the head unit is off) but when the head unit is on, it doesn't display anything or actually let you use any functions (seeming like it has no power). It has done this with both stereos, so I'm guessing it's something with the car's wiring. Is it a bad fuse even though it is getting power? A bad wire (power wire)? With the new stereo, when you first turn the key, the display will illuminate for a split second, then nothing, just the limited power like before. The car is a 1987 Caddilac Brougham (like Fleetwood). Thanks.
sounds like the constant power( the yellow wire) is getting power hook both of your power wires together and turn the switch on and see if you get everything then, if so find a constantly on power wire for the yellow and connect it there and leave the red wire on switched power
