Radio (Delco) question

[Guest]

Guys, my 63 Lark's Delco AC-3351 radio has three flat slider-type terminals on the back and I'm trying to determine which is which. The prev. owner had everything disconnected when I got the car and I've had the radio serviced. Now it's time to plug things back in and there are no markings to indicate what's what.
Any help would be appreciated. Thanks!

On the radio, the terminal nearest the corner is +12V. Center is audio out, to speaker. Farthest from corner is ground for speaker. The radio grounds through it's chassis, to the dash.
The original speaker had two wires, to a plastic shell that made connections to the above mentioned ground and center contacts. It had a socket for the +12V connector.
If you had a fader and rear speaker, it's connector went between the radio and the connector for the front speaker.
The metal terminals are 1/4" QD, with a barb to hold them in the plastic shell. Rhode Island wire has them.

Mike thanks a bunch. I didn't want to plug 12v into a speaker ground by mistake. :-)
