Hello everybody, I bought this car about a year ago and it had an aftermarket radio in it which worked great despite being a little old. I decided I wanted to replace it with a newer model, took it out only to realize I needed a new wiring harness. I put everything back together and found that my clock stopped working as well as my radio and power antenna. The airbag light came on too. I just bought a new wiring harness for the other radio, installed it, checked every fuse, and plugged the radio in. Still nothing. Does anybody have any advice for me? Thanks in advance.

Hi,

You have a power loss. Where are you taking power from? If you look at pic 1 below, it shows the power supply for the original radio. Check both fuses and if they are good, confirm they are getting power from the fuse box. Here are a few links to help:

Now, if you look at picture 2, it indicates power to the air bag control module is the same as one of the original radio power supplies, fuse 20. So with that, I suspect that fuse is blown. If it is, replace the fuse with the same amperage, 10 amp. Do not up size the fuse.

Check that and let me know the results.

Take care,
Joe
