I need help with a simple install

[edpdx]

I pulled this AM/FM Stereo Cassette out of a 73 Cougar. I didn't make wiring notes when I pulled it. I figured out the power and ground pair; but the remaining speaker pair and ground... I am not sure. Anyone remember what RCA likes to color left and right pairs?

The Model: RCA 20C515F

RED/YELLOW PAIR 1? BLUE/WHITE PAIR 2? AND A BLACK GROUND WIRE. How do you wire this to one pair of speakers?

Can anyone recommend a site to get RCA schematics? I'd go out on a limb and TRY something; but I don't want to fry a channel or something... best guess... anyone, anyone?

back then they used a common ground system - so each speaker output shared the ground cable - which would probably be black. you can use the fader and balance to determine which wire is which. either use a test speaker or a DMM to measure VAC out with a signal and fader/balance set to one speaker at a time.
