Hello, I am having trouble with an after market radio in my 94 zx. The old one worked just fine. I hooked up the new one and it does not work. I have constant power to the yellow wire but no power at all to the red ignition wire even when car is on! I am not quite sure if the red wire is the ignition wire. I believe all my fuses are good, I have checked them and made sure there working. I just bought this car so I do not know much about it.

Thanks!

I am new to this forum so if I post this in the wrong area please forgive.

 

hook up the old one, If that works, then maybe the new stereo is a dud.
