1997 Dodge Stratus need help

You connected the radio's ground wire to the dash light wire. Very common mistake because the low resistance makes it check like a ground wire. There is no ground wire in the two connectors. That's why there was a braided ground strap bolted to the original radio, or it had a black ground wire clipped to the radio.

There are two fuses for the radio. The station preset and clock memory fuse will be tied into a different circuit that is always hot such as the horn or interior lights.
