There should be a red and orange and a couple of dark colored wires. Red goes to power, orange to lights, other 2 wires to the speaker. Add the antenna and ground the radio case, turn it on and hope that the radio plays. I bought a known not working A Body knob style AM/FM from another member and sent it to Gary Tayman to be converted. Looks brand new with 4 speaker capability and aux input for other stuff.
