Old radio never worked. I bought the harness to use swc and harmon kardon amp. I have everything connected to check for power only, no sound. No power to radio. Fuses are good to radio. With a test light, both fuse terminals light up.

Any ideas?

 

I would say bad AMP

 

Also, forgot to mention-radio itself doesn't turn on either.

 

My Harmon Kardon adaptor has "key 1" & "key 2"

Do we need to connect those? The radio harness that came for the power Acoustik doesn't have a key 1 or key 2.
