I'm hoping some of you guys can help me. A month or so ago I installed a new CD player in my 2003 GT. I used a Metra 70-5519 wiring harness from Best Buy. I ended up running separate wiring to each speaker because the previous owner removed all of the amplifiers and the rear sound bar in the vehicle.
Everything went smoothly, but I accidentally ran the illumination power and illumination ground wires together to the 12v power wire. I have no idea how I did this, but I did. I removed the illumination wires completely so they are not connected. Unfortunately in the process my dash lights no longer work. All of the seat belt, airbag, check engine, etc lights work, but the speedometer, tachometer, engine oil temp, water temp gauges do not have any back light anymore. The gauges themselves work fine, just no lights so I can't see them at night. I have already replaced the headlight switch thinking that I might have blown something internally, but it made no difference. I have checked all of the fuses numerous times and they are all fine. I double and triple checked my wiring, but everything is correct. I just pulled the gauge cluster out a few days ago and checked all of the bulbs, but they are all fine. I even swapped them around with known working bulbs and they are definitely all good.
Can anyone give me any hints on what to check next? I don't care what I have to replace, I just need to get it done! I can't drive my Mustang at night and this is getting really old!
Thanks for anyone's help!
