I just bought this old Fiat radio. Im lost with this wiring. Theres a blue and white wire, a purple and white, a solid blue, and 2 ground i believe (2 grounds dont make sence) What color goes with what? Thanks
So i believe the solid blue is power, the black and white is ground and the other for are speaker. Ive located the speaker wire on the fiat. What color would power and ground be on the fiat?

I'm not sure of how it should be wired but you may want to make sure it fits into the console. I have a early Fiat radio I tried to install in my 72 and the body was too long and was hitting the heater box.

The blue with the inline fuse is the hot power lead that will go to the switched wire from your ignition harness. The wire screwed to the side of the body of the radio is the ground and can be replaced with a new lead.
The two pairs of wires with bullet connectors go to the speakers. Using a test light (preferably an LED one), once you have power to the unit, you can test which one is the power and which is the ground (the wire with the second color trace on it should be the ground given the male bullet connector on it).
Bullet connectors are good, positive connectors and should be used with a stereo. Spade connectors have a bad tendency to pull apart.

since there were no factory installed radios, that means that all were installed after market. guess what?
aftermarket installations guaruntee zero uniformity. a male bullet terminal "should" signify ground is as reliable as the person that installed the bullet terminal. additionally, the positive and negative "shoulds" to the speakers are as reliable as that installer.
take nothing for granted. pull the speakers and check for the + and - symbols on your speakers, and follow Karl's advice with the test light.
quite honestly, i would have guessed that an early 70's radio would still have used the chassis for speaker grounds.
